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

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)
