Possible solutions: 1) org.openide.explorer.ExplorerManager$Listener.nodeDestroyed() - lock free or reorder locks (take CH.mutex (exclusive) before obtaining the monitor). 2) Changing the org.openide.nodes.Node.fireNodeDestroyed() not to fire under lock may be dangerous, so the ExplorerManager$Listener.nodeDestroyed can do reschedule. 1st seems safer to me. already fixed in #237545 (sol. #1 chosen) *** This bug has been marked as a duplicate of bug 237545 *** |
Created attachment 140249 [details] Threads Dump See attached threads dump. AWT: holds ExplorerManager$Listener and tries to acquire Children mutex (shared). Module-Actions: hods Children mutex (exclusive) calls ExplorerManager$Listener.nodeDestroyed tying to obtain lock. Both ExplorerManager$Listener and org.openide.nodes.Node are wrong. They are calling untrusted code under lock.
