Description mchristi 2009-01-12 13:21:45 UTC 
Build: NetBeans IDE 6.5 (Build 200811100001)
VM: IBM J9 VM, 2.4, Java(TM) SE Runtime Environment, jvmxa6460-20081105_25433
OS: Linux, 2.6.27.9-159.fc10.x86_64, amd64

User Comments:
mchristi: I have an output window that is minimized.  I opened it and wanted to dock it into the same pane where my tasks window is.  Then the GUI started to behave strangely (some parts weren't redrawn as expected).

Looks like a race condition. Perhaps CodeFoldingSideBar.Listener should repost events that are not delivered in AWT
thread to that thread to make sure that cache and visibleMarks are accessed only from AWT.

Marek, these are yours now ...
Comment 5 Svata Dedic 2011-10-10 12:02:03 UTC 
WFM - visibleMarks is only accessed from AWT (paintComponent, scheduled by invokeLater to AWT; mouse event handler called in AWT). Must have been fixed in the past.
