Hello,
Please review the following fix for Jdk9: Bug: https://bugs.openjdk.java.net/browse/JDK-8030099 Webrev: http://cr.openjdk.java.net/~rchamyal/8030099/webrev.00/ Issue: The memory usage of java process goes on increasing if we call ShellFolder:listFiles API aggressively on some folder with large number of files/folders. Cause: Win32ShellFolder class registers its instances and native data with sun.java2d.Disposer class for later disposal. Win32ShellFolder instances are getting registered as PhantomReferences with Disposer and are not getting cleared immediately. This leads to increase of memory usage by java process. Fix: Instead of registering the complete Win32ShellFolder object reference with disposer we are now adding only a sentinel object and also using sun.java2d.Disposer :: addObjectRecord API which adds the references as WeakReferences. Regards, Rajeev Chamyal
