Stack dump

Dev 201105030 - 20110608

If I create a JPanel GUI component, select JButton from the palette, and Shift click to add multiple buttons, it freezes after the 2nd or 3rd click and I have to kill it with TaskManager.

I'm attaching the output of jstack -l

Bumping priority up.

This appears to be triggerable by any quick series of GUI changes.
This time it was deleting a button, then pressing Ctrl-Z to undo it.

Comment 3 Jan Stola 2011-06-10 05:09:57 UTC 
It seems like a deadlock between AWT-EventQueue-1 and Data System Nodes introduced by jtulach's attempt to fix issue 199136 (i.e. by introduction of FolderChildren$DelayedNode). Reassigning to platform/Data Systems.
