Comment 2 Miloslav Metelka 2007-01-17 17:13:44 UTC 
This seems to be the following situation:
1) AWT waits for a document to write-lock it
2) Tooltip evaluator calls Debugger's tooltip annotation under the readlock.
3) As the SwingUtilities.invokeAndWait() gets called by the annotation there is
a deadlock.
Reassigning to debuggerjpda whether you can eliminate
SwingUtilities.invokeAndWait() from your code.
Comment 3 Martin Entlicher 2007-01-22 17:15:30 UTC 
This is hopefully fixed by the fix of issue #92773. Please verify.

Verified ... and Closing all issues resolved into NetBeans 6.7 and earlier.
