Comment 2 David Strupl 2009-10-01 09:08:16 UTC 
The problem is that SourceLevelQueryImpl.getSourceLevel took 32 seconds in thread "openide.text document processing". It
was blocked by the computation of apisupport in thread "Java Node Badge processor" which was most probably triggered by
the Hg refresh. Assigning to apisupport to evaluate.
Comment 3 mslama 2009-10-01 09:38:55 UTC 
Problem is that debugger calls openDocument in AWT thread. It should be done from another thread as this call is
blocking and can take long time.
Comment 4 Jaroslav Tulach 2009-10-01 09:40:20 UTC 
This is problem of the caller to openDocument. That call just cannot be absolutely fast, so it shall not be called 
from AWT. Assigning to WatchPanel.setupContext().
