The test:

 java/lang/invoke/condy/CondyInterfaceWithOverpassMethods.java

triggers a jtreg failure on Windows:

test result: Error. failed to clean up files after test

The test contains:

        // For debugging purposes
        new FileOutputStream(new File(genClassName + ".class")).write(byteArray);

and this file is never closed. This may result in an issue in agentvm mode when jtreg tries to delete the file.
