      Found 1 deadlock.

      Comment added by mmikucionis(###@###.###) :
      It seems that the fix is not good enough. I use JDK 1.6.0_14 and get deadlock when Label.setText is involved, i.e. the code at sun.awt.X11.XTrayIconPeer$Tooltip.display(XTrayIconPeer.java:677) should also be executed on EDT to avoid deadlock.
