Noting to do with Output Window.
org.netbeans.modules.editor.completion.CompletionImplProfile initiates write of sampler data in AWT.
Defect in editor or sampler.
Comment 6 Dusan Balek 2011-01-11 16:09:12 UTC 
Seems like a problem with sampling.
Comment 7 Jaroslav Tulach 2011-01-12 08:24:09 UTC 
According to 
http://statistics.netbeans.org/exceptions/exception.do?id=390587
the Sample.close(), can take quite a lot of time. The close happens on AWT thread (mistake?) and is itself detected as slowness. Tomáši, what is your advice in this case? We probably need to move the long action outside of AWT. Where the thread switch shall happen?
