sorry i had no chance to evaluate it...
There is a DL between Active Reference Queue Daemon and org.netbeans.spi.project.ui.support.NodeFactorySupport
However no sure whose fault is that, maybe NodeFactorySupport$DelegateChildren.removeNotify could avoid asking for the lock in Active Reference Queue Daemon?

Node for important files in Web Project is no longer created in the NodeList.keys() method, so DataObject.getNodeDelegate() is not called under NodeFactorySupport$DelegateChildren lock any more.

Many thanks to Tomas Hurka and Tomas Mysik for help.

Tomáši, I assume that verification of this bug fix is not easy if not possible at all, am I correct?
