Description sasule 2011-12-13 12:37:16 UTC 
This bug was originally marked as duplicate of bug 179002, that is already resolved. This bug is still valid, so this seems to be another bug, but it might be related.

AWT thread is blocked on Children.MUTEX.readAccess in:

org.openide.nodes.Node.isLeaf()	5719 ms/0.000 ms

The write access seems to be hold by Active Reference Queue Daemon trying to garbage collect 

org.netbeans.spi.project.ui.support.NodeFactorySupport$DelegateChildren.removeNotify()	5719 ms/0.000 ms	1

this call is probably blocked by org.netbeans.spi.project.ui.support.NodeFactorySupport thread calling from
org.netbeans.spi.project.ui.support.NodeFactorySupport$DelegateChildren$1.run()	100.0	5719 ms/4270 ms
to org.netbeans.modules.php.project.ui.logicalview.ImportantFilesNodeFactory$ImportantFilesChildrenList.keys() 5719 ms/4270 ms

Comment 5 dijedodol 2013-05-22 09:17:30 UTC 
I kept having this performance problem when I have enabled xrender, this things mostly happens when my netbeans console windows is printing a lot of text.
Comment 6 Tomas Stupka 2016-06-24 14:44:22 UTC 
going through some recent reports org.netbeans.spi.project.ui.support.NodeFactorySupport doesn't seem to be involved

please reevaluate

(btw, no reports since 8.0.2)
