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 it would not be too bad to offload AWTTreeLock methods ourselves, i.e.: boolean wait = false; AWTEDTExecutor.singleton.invoke(wait, new Runnable() { @Override public void run() { ... detach .. or attach .. } } ); +++ "J3D-Renderer-1" prio=5 tid=0x00007f96dceaf800 nid=0xe103 waiting for monitor entry [0x000000011d9d5000] java.lang.Thread.State: BLOCKED (on object monitor) at java.awt.Component.removeHierarchyListener(Component.java:5383) - waiting to lock <0x00000007f8127338> (a java.awt.Component$AWTTreeLock) at com.jogamp.nativewindow.awt.JAWTWindow$JAWTComponentListener.detach(JAWTWindow.java:175) at com.jogamp.nativewindow.awt.JAWTWindow$JAWTComponentListener.access$600(JAWTWindow.java:123) at com.jogamp.nativewindow.awt.JAWTWindow.destroy(JAWTWindow.java:606) at javax.media.j3d.JoglDrawable.destroyNativeWindow(JoglDrawable.java:60) at javax.media.j3d.JoglPipeline.destroyContext(JoglPipeline.java:6799) at javax.media.j3d.Canvas3D.destroyContext(Canvas3D.java:4651) at javax.media.j3d.Renderer.removeCtx(Renderer.java:1551) - locked <0x00000007f841de58> (a java.lang.Object) at javax.media.j3d.Renderer.doWork(Renderer.java:372) at javax.media.j3d.J3dThread.run(J3dThread.java:271) +++ See <http://forum.jogamp.org/JOGL-commit-166e5da-causes-deadlock-errors-in-Java-3D-tp4031305.html> 3665 1 sgothel 2014-01-27 18:17:31 +0100 b7fafd30ffc5eac73880b264043582d74175a394 Resolved as described
