Description Jan Lahoda 2010-05-11 12:30:44 UTC 
Created attachment 98758 [details]
Two full thread dumps.

After:
http://hg.netbeans.org/main-silver?cmd=changeset;node=894fe07157c0
the IDE deadlocks for me a lot. Two full thread dumps attached, one happened during initial scan, second during refactoring. The problem (IMO) is this:
-priority I/O locks the (background) refresh
-but the (background) refresh is already running, and has write lock on mutex ChildrenCache.getPriorityMutex() - taken in FolderObj.refreshImpl, and waits until the priority I/O finishes.
-the callable inside the priority I/O tries to do something with fileobjects, which requires read lock mutex, but this cannot be acquired.
