* @test
*
* @summary converted from VM Testbase nsk/jdwp/VirtualMachine/RedefineClasses/redefinecls001.
* VM Testbase keywords: [quick, jpda, jdwp, redefine]
* VM Testbase readme:
* DESCRIPTION
* This test performs checking for
* command set: VirtualMachine
* command: RedefineClasses
* Test checks that debugee accept the command packet and
* replies with correct reply packet. Also test checks that
* after class redefinition invocation of static and object
* methods resuts in invocation of redefined methods, and
* no constructors are invoked.
* Test consists of two compoments:
* debugger: redefinecls001
* debuggee: redefinecls001a
* First, debugger uses nsk.share support classes to launch debuggee
* and obtain Transport object, that represents JDWP transport channel.
* It also loads bytecode of redefined class from *.klass file.
* Next, debugger waits for tested classes are loaded, and breakpoint
* before class redefinition is reached.
* Then, debugger creates command packet for VirtualMachine.RedefineClasses
* command for the found classID and loaded bytecode, writes this packet
* to the transport channel, and waits for a reply packet.
* When reply packet is received, debugger parses the packet structure
* and checks if no reply data returned in the packet.
* Then, debugger resumes debuggee to allow methods of redefined class
* to be invoked and waits for second breakpoint is reached.
* Upon their invocation redefined methods puts proper value into
* the special static fields of debuggee class. The debugger then
* checks these fields to verify if the redefined methods were invoked
* and no constructors were invoked.
* Finally, debugger disconnects debuggee, waits for it exits
* and exits too with the proper exit code.
* COMMENTS
* First positional argument for the test should be path to the test
* work directory where loaded *.klass file should be located.
* Test was updated according to rfe:
* 4691123 TEST: some jdi tests contain precompiled .klass files undes SCCS.
* redefinecl001b.ja was moved into newclass directory and renamed
* to redefinecl001b.java.
* The precompiled class file is created during test base build process.
