Bug 952 - JAWTWindow.JAWTComponentListener's ctor() and detach() may deadlock due to AWTTreeLock acquisition while add/remove AWT listener
The AWTTreeLock is acquired by Component.removeHierarchyListener and as for _every_ AWT component, modifications shall happen on the AWT-EDT. IMHO the user shall offload AWT modifications to the AWT-EDT similar to what JOGL's GLCanvas and NEWTCanvasAWT does. However, since JAWTWindow also represents a NativeWindow instance we shall offload AWTTreeLock methods ourselves!
