REGRESSION.  Last worked in version 6u45


REPRODUCIBILITY :
This bug can be reproduced occasionally.

The java.util.Comparator implementation that is used in sun.awt.shell.Win32ShellFolder2$18.call is reduced to IShellFolder::CompareIDs Win32 API call. I cannot reproduce the issue by calling ShellFolder.sortChildren() in JDK 8u40 on Windows. A test or more detailed description is required to continue.

There is not enough information in the report. However, based upon limited stack trace it looks like a duplicate of JDK-8048887. I have written back to the submitter requesting more information including confirmation about the bug reproducibility with latest JDK versions 8u60 and 9 ea. ======================================== On 9/3/2015 9:25 AM, Pardeep Kumar Sharma wrote: > Hi ......., > > Can you please confirm if this issue is reproducible with the latest JDK versions 8u60 and 9 ea b78. > > You can download the respective from: > http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html > https://jdk9.java.net/download/ > > Further, if you could share more information including a test case to reproduce this issue, will help. > > Thank You, >............ =========================================================
