I showed cvs diff for two projects. Then I switch to editing ofa file  and
switch back to diff view after few modifications.

Found one Java-level deadlock:
=============================
"Default RequestProcessor":
  waiting to lock monitor 0x0809f814 (object 0x7f384510, a
java.awt.Component$AWTTreeLock),
  which is held by "AWT-EventQueue-1"
"AWT-EventQueue-1":
  waiting to lock monitor 0x0809f8d4 (object 0x82a880c8, a
org.netbeans.modules.diff.builtin.visualizer.editable.EditableDiffView),
  which is held by "Default RequestProcessor"
