                To support JDK 9 image file as an archive the FileUtil's method
                <code>getArchiveFile</code>,<code>getArchiveRoot</code> and <code>isArchiveFile</code>
                are pluggable using a new SPI <code>ArchiveFileProvider</code>.
                In addition to these methods a new method <code>isArchiveArtifact</code> was added.
                This method can be used if given <code>URL</code> points into an archive.

                To support multiple configurations (users, profiles, ...) executing in the same VM, multiple
                Repositories can be created, one for each execution context. API has been added to acquire 
                and SPI to create a local Repository which holds config filesystem for the execution thraed.

                    The FileSystem.Status was entirely removed, as it references class java.awt.Image, which 
                    is not available in compact jdk profiles and may trigger GUI system initialization. See

                    The default implementation of FileSystem.Status annotated file's icon using ImageUtilities
                    which uses AWT graphics etc. Such dependency is not desirable in a standalone FileSystem API
                    library.
                </p>
                <p>
                    The builtin implementation now does not work with the icon at all and returns null. A proper
                    implementation for FileSystem.Status is looked up in default Lookup and is implemented
                    properly (with Icon annotations) in <code>openide.filesystems.nb</code> module.

                    There are new annotations to register mime type. One
                    can either use simpler ones based on
                    <a href="@TOP@/org/openide/filesystems/MIMEResolver.ExtensionRegistration.html">
                    extension</a> or

                    XML namespace</a>. In case these registration are not
                    powerful enough one can use the original and flexible 
                    <a href="@TOP@/org/openide/filesystems/MIMEResolver.Registration.html">
                    XML file based registration</a> which is however processed
                    during compile time to avoid needless XML parsing on each
                    start.

                    FileObject.DEFAULT_LINE_SEPARATOR_ATTR defines file object attribute name to get default line separator.
                    File object can provide default line separator if it differs from
                    <code>System.getProperty("line.separator")</code>. Call
                    <code>fo.getAttribute(FileObject.DEFAULT_LINE_SEPARATOR_ATTR)</code> returns string with
                    default line separator. Default line separator will be used by the text
                    editor if saving new content to an initially empty file. Any other code
                    which creates file content programmatically must manually read this
                    property if it cares.

                    Modules need no longer declare runtime-only dependencies
                    on other modules merely to override their layer entries.
                    Instead, they should specify a higher weight.
                    (Normally the base module will declare no weight, so any
                    positive number will do.)

                    <code>MultiFileSystem</code>s will now interpret a special
                    file attribute <code>weight</code> to determine how to
                    resolve otherwise ambiguous overrides. For example, in the
                    system filesystem, module XML layers can use this attribute.
                    Suppose a generic infrastructure module declares:
                </p>
                <pre>
&lt;filesystem>
    &lt;folder name="my-snippets">
        &lt;file name="common.xml" url="generic-snippet.xml"/>
    &lt;/folder>
&lt;/filesystem>
                </pre>
                <p>
                    If another module wishes to override this declaration, it
                    can do so by specifying:
                </p>
                <pre>
&lt;filesystem>
    &lt;folder name="my-snippets">
        &lt;file name="common.xml" url="special-snippet.xml">
            &lt;attr name="weight" intvalue="100"/>
        &lt;/file>
    &lt;/folder>
&lt;/filesystem>
                </pre>
                <p>
                    This override will work even if the module system happens
                    to load the specializing module <em>before</em> the infrastructure
                    module (as could happen if there is no module dependency
                    between them). The weight attribute also makes it clear that
                    something is being overridden.

                    to scan its XML files for definition of <code>attrName</code>
                    attribute and <i>guess</i> its class. The <i>guessing</i> is
                    usually easy, just for <code>methodvalue</code> types, the system
                    needs to use some kind of heuristic: it locates the
                    appropriate factory method and returns its return type. This may
                    not be the actual type of the returned object at the end, but
                    it seems as the best guess without instantiating it.

                    Declaratively registered MIME resolvers using the XML file syntax
                    (rather than Java classes implementing <code>MIMEResolver</code>)
                    are now used even when you run an application with just the Filesystems API in the classpath.
                    In particular, this makes declarative resolvers be honored in unit tests.
                    Formerly, declarative resolvers were only loaded when you used <code>org-netbeans-core.jar</code>
                    and started the full module system.

                    There are now various methods in <code>FileUtil</code> that let you
                    easily convert between archive files themselves and their entries. It
                    is no longer necessary (or advisable) to explicitly construct
                    <code>JarFileSystem</code>s to work with archives. A standard
                    <code>URLMapper</code> implementation is present which handles
                    <code>jar</code>-protocol URLs correctly.

                    There is no direct replacement. Code using this method should be

                    In NetBeans 3.x, normally “compilation” or similar build
                    steps would produce generated files kept in the user’s
                    development folder alongside source files, and picked up as secondary
                    files by a <code>MultiFileLoader</code>. To ensure that the VCS
                    integration did not offer to version such files,
                    <code>FileObject.setImportant</code> could be used to mark them as
                    disposable.
                </p>
                <p>
                    In NetBeans 4.0, such disposable files should not be placed in a source
                    folder. They should always be built to a separate build directory,
                    typically defined by the containing project. In this case marking an
                    individual file as unimportant is unnecessary, since the entire build
                    tree is known to be disposable. Instead, the project (not data loaders)
                    can use <code>SharabilityQueryImplementation</code> to indicate which
                    subtrees contain build products.

                    Various parts of the Filesystems API which are no longer useful in
                    NetBeans 4.0 were deprecated. The assumptions which are now invalid
                    were:
                </p>
                <ul>
                    <li>
                        <p>
                            The root of a filesystem corresponds to a Java classpath root (if
                            the appropriate capabilities were set). Now handled by the
                            Classpath API.
                        </p>
                    </li>
                    <li>
                        <p>
                            The user explicitly mounts and unmounts filesystems, either to
                            control the classpath, for version control purposes, or simply to
                            access some area of the disk; and so filesystem metadata is
                            relevant to the GUI. Now obsoleted by the Classpath API and
                            MasterFS.
                        </p>
                    </li>
                    <li>
                        <p>
                            The IDE internally managed a list of mounted filesystems. Now only
                            the default system filesystem is “mounted”; MasterFS
                            transparently manages all “user-space” files.
                        </p>

                        <p>
                            File objects are persisted by saving a reference to the containing
                            filesystem, plus the relative path within the filesystem. Now done
                            using URLs.

                    Older Filesystems API clients which assumed that
                    <code>FileObject.toString()</code> and

                    <code>FileObject.toString()</code> no longer returns a predictable
                    value; in particular, it will not be the same as
                    <code>getPath()</code>. The new value is suitable for logging and
                    debugging but otherwise cannot be relied upon.

                            The new <code>toString()</code> is more useful for logging than the
                            previous value. It is no longer necessary to separately include
                            <code>fileObject.getFileSystem().toString()</code>, which was
                            cumbersome (and required an extra catch clause).

                            fixed to use <code>ClassPath</code>. (The paths would not have been
                            usable in NetBeans 4.0 anyway.) Just deprecating
                            <code>toString()</code> was not possible because it overrides a
                            nondeprecated <code>Object</code> method, and is also inserted into
                            code by the compiler without emitting any deprecation warning.

                Repository is not final anymore, so there can be subclasses of it. But all its methods

                    The deprecated classes continue to be available in the module
                    <code>org.openide.deprecated</code> which you may depend on it you
                    cannot remove uses of the deprecated APIs. In order for
                    <code>TopManager.getDefault()</code> to work, you must also require the
                    token <code>org.openide.TopManager</code>, which is provided by an
                    unspecified module. The deprecated API module and its implementation
                    module are autoloads, meaning they will not be loaded unless some
                    module still requires them.
                </p>
                <p>
                    Similarly, the Java Hierarchy API was moved to the module
                    <code>org.openide.src</code> which you should depend on in order to use
                    this API.

                <p>
                    For compatibility, the above three dependencies are added to your module
                    <em>automatically</em> in case it either requests no specific API
                    version at all, or requests an API version prior to 3.14. Modules
                    requesting APIs 3.14 or higher must declare these dependencies
                    explicitly if they in fact need them.

                    Many classes were moved to a separate module,
                    <samp>openide-deprecated.jar</samp>, not available to modules by
                    default. Uses of these classes in modules should be cleaned up whenever
                    possible.
                </p>
                <p>
                    Additionally, the entire contents of <code>org.openide.src.*</code> and

                    <code>org.openide.cookies.SourceCookie</code> and some associated
                    property editors, were moved to a separate module.

                <p>
                    The most common apparent symptom for module authors will be the absence
                    of <code>TopManager</code>. Most methods in this class have been
                    replaced by newer utility classes in a straightforward manner. See the

                    Module authors using the now-separated APIs will need to adjust their
                    compilation classpaths to include the new JAR files. Modules wishing to
                    use recent APIs and declaring a current openide specification version
                    dependency will need to explicitly declare dependencies on these new

                    automatically refined as if to include the declarations:

                    Three sections of the Open APIs were split into new autoload modules.

                <ul>
                    <li>

                            The module <code>org.openide.compiler</code> (version 1.0) contains
                            the Compiler API and some other classes directly related to it.
                        </p>

                            the Execution API and some other classes directly related to it.
                        </p>

                    <li>
                        <p>
                            The module <code>org.openide.io</code> (version 1.0) contains
                            <code>InputOutput</code> and related classes (formerly part of the
                            Window System API, and still physically in the
                            <code>org.openide.windows</code> package).

                    New modules wishing to use these APIs must declare regular module
                    dependencies on them. Future changes in these APIs will be documented
                    separately.

                    Furthermore, modules wishing to use certain services must
                    <code>OpenIDE-Module-Require</code> them if appropriate:

                            <code>AbstractCompileAction</code> or one of its subclasses, or
                            call <code>CompilerJob.start()</code>, or use
                            <code>BeanInfo</code>s for Compiler API classes, etc.

                            <code>Executor.execute(...)</code>, or use <code>BeanInfo</code>s

                            and add it to Lookup instead.

                            All uses of <code>ExecInfo</code> are deprecated as they abuse the
                            distinction between Filesystems and the user classpath. Use and
                            override only <code>Executor.execute(DataObject)</code>. Similarly,
                            <code>ThreadExecutor</code> is deprecated for the time being
                            because it suffers from similar problems.

                            Direct use of <code>NbfsURLConnection</code> is deprecated in favor
                            of the more general <code>URLMapper</code> from the Filesystems
                            API.

                            with module dependencies on a new autoload module
                            <code>org.netbeans.lib.terminalemulator</code> (version 1.0).

                            Several static convenience methods have been added to
                            <code>AbstractCompileAction</code>. Of most interest is
                            <code>prepareJobFor</code>. Module code should no longer assume
                            that <code>DataFolder</code> has a <code>CompilerCookie</code>
                            which recursively compiles the folder and subfolders (according to
                            depth); while it is still true, for reasons of compatibility, new
                            code should use <code>prepareJobFor</code> to create a compiler job
                            from a folder.

                It is commonly necessary to find the full resource path of a file object
                within its filesystem. Formerly you could do this the safe way by calling
                <code>getPackageNameExt('/', '.')</code>, but this is clumsy to
                write, potentially inefficient, and is prone to misinterpretation in the
                case of files without any extension (or files ending in a period, or
                folders with extensions). Calling <code>toString()</code> was more
                effective, but this suffered from the problem that for compatibility
                reasons, no assurance could be made that it would actually give a
                resource path - an old <code>FileObject</code> implementation could
                implement it in any way, since it was not originally documented what it
                should return. Therefore, the new method <code>getPath()</code> has been
                introduced.

                    It used to be the case (NB 3.2) that a FileSystem
                    implementation could in its BeanInfo specify a BeanDescriptor whose
                    Customizer class extended WizardDescriptor. This would cause the
                    wizard to be opened when the user tried to mount that filesystem type.
                </p>
                <p>
                    The situation now (from 3.3) is that this no longer opens
                    the customizer and property sheet is presented in the second
                    step of the mount wizard.

                    that would only be called from within the class itself.) These methods

                    In general, outside code should use the proper outer API to access
                    filesystems (<code>FileSystem</code> and <code>FileObject</code> and
                    some helper classes), only directly calling methods of implementation
                    classes where this is required (constructors or
                    <code>setRootDirectory</code>). As a matter of style, it is recommended
                    that calling code declare variables to be of the abstract type (e.g.
                    <code>FileSystem</code>) to clarify that only generally available
                    methods will be called.

                There was made changes in FileObject class.
                Added method: <code>public boolean canRead ()</code>.
                Method  <code>public boolean isReadOnly ()</code>  was deprecated and replaced with
                method: <code>public boolean canWrite ()</code>. This change can be considered as compatible.
                Newly added methods have default implementation.  Also AbstractFileSystem was modified and two
                necessary method were added: method: <code>public boolean canRead ()</code> and 
                method: <code>public boolean canWrite ()</code>.

                appropriate <code>java.io.File</code> to <code>FileObject</code> if
                possible. If not possible then <code>null</code> is returned.
                Also added method <code>public FileObject[] fromFile(File)</code>. Finds
                appropriate <code>FileObject</code>s to <code>java.io.File</code> if
                possible. If not possible then empty array is returned. More than one
                <code>FileObject</code> may correspond to one <code>java.io.File</code> so
                an array is returned.

            <h2>What do the Dates Mean?</h2>
            <p>
                The supplied dates indicate when the API change was made, on the CVS
                trunk. From this you can generally tell whether the change should be
                present in a given build or not; for trunk builds, simply whether it
                was made before or after the change; for builds on a stabilization
                branch, whether the branch was made before or after the given date. In
                some cases corresponding API changes have been made both in the trunk
                and in an in-progress stabilization branch, if they were needed for a
                bug fix; this ought to be marked in this list.
