NetBeans cannot be used after this error happens. Almost everything stops working, even the close button of NB. I have to kill the process in order to stop NetBeans.

before installing a new DEV version. It happened for me several times to keep seeing an issue after it being fixed because of some kind of problem generated by not deleting the userdir before installing a new NetBeans. See if that helps and remember this trick for later on. I can confirm that the error stopped appearing in build from 10th of May. Cheers!
