Description: JDK 13 introduced a source compatibility issue
 Quote from the Java release notes:
 The addition of newFileSystem(Path, Map<String, ?>) creates a source (but not
 binary) compatibility issue for code that has been using the existing 2-arg
 newFileSystem(Path, ClassLoader) and specifying the class loader as null. [...]
 To avoid the ambiguous reference, this code needs to be modified to cast the
 second parameter to java.lang.ClassLoader.
