Public bug reported: As a NetBeans IDE developer, I am frequently launching the IDE (a Swing- based Java application) in one or more copies. From time to time when opening the IDE main window (i.e. a javax.swing.JFrame) while running Unity 2D, unity-2d-panel suddenly crashes, leaving a blank space (showing the screen background) where the panel normally is. The window manager continues to work, so I can switch between apps using Alt-TAB, but the panel and all its applets are gone.
Running 'killall -HUP unity-2d-panel' restores the panel in this case, meaning I guess that the process was still alive but somehow not responding. I have not yet managed to pinpoint the exact conditions under which this bug happens. Generally it is when I already have one copy of NetBeans running and then run a second (testing) copy, though this does not reliably trigger the bug by any means. I use (Oracle) JDK 6u31 and 7u3, both in the 32-bit version. Will attach a redacted copy of my ~/.xsession-errors from the current session. You can see several instances of "WARNING: Application 'unity- 2d-panel.desktop' killed by signal" - any immediately preceding messages might be related to the crash.
