Public bug reported: The latest security update of OpenJDK 6 appears to have broken NetBeans and other NetBeans platform based applications such as VisualVM. It may break many other Swing applications - not tested. Manifests as UI issues, NPE's and lockups (eg. find usages dialog hangs NetBeans). One stack trace shows EventQueue.isDispatchThread() returning false from within the dispatch thread.
All is fine in current OpenJDK 7. Looking at NetBeans on OpenJDK 6 from VisualVM (running on 7!) shows multiple AWT event queues and sometimes deadlock between them. Same result is not seen when running NetBeans with OpenJDK 7. Running on 12.04 with OpenJDK-6-JRE 6b27-1.12.6-1ubuntu0.12.04.2 ** Affects: openjdk-6 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1204906 Title: NetBeans, VisualVM, etc. broken with latest security release for 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openjdk-6/+bug/1204906/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
