Hello, I know that the ERXShutdownHook has been added in order to stop the ERJGroupsSynchronizer correctly. May be it's worth upgrading at least to Wonder 6 ;-)

The stack trace points to an error in ERXObjectStoreCoordinatorSynchronizer$ProcessChangesQueue.stop "Attempted to stop the ProcessChangesQueue when it wasn't already running". I don't really care about that error, I just want the instance to shut down, but this stops the normal shutdown process. Any ideas? … Caused by: java.lang.IllegalStateException: Attempted to stop the ProcessChangesQueue when it wasn't already running at er.extensions.eof.ERXObjectStoreCoordinatorSynchronizer$ProcessChangesQueue.stop(ERXObjectStoreCoordinatorSynchronizer.java:618) at er.extensions.eof.ERXObjectStoreCoordinatorSynchronizer.stopRemoteSynchronizer(ERXObjectStoreCoordinatorSynchronizer.java:132) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at com.webobjects.foundation.NSSelector._safeInvokeMethod(NSSelector.java:122) at com.webobjects.foundation.NSNotificationCenter$_Entry.invokeMethod(NSNotificationCenter.java:588) at com.webobjects.foundation.NSNotificationCenter.postNotification(NSNotificationCenter.java:532) at com.webobjects.foundation.NSNotificationCenter.postNotification(NSNotificationCenter.java:546) at er.extensions.appserver.ERXApplication.terminate(ERXApplication.java:2733) at com.webobjects.appserver.WOApplication._terminateFromMonitor(WOApplication.java:3607) at com.webobjects.appserver.WOAdminAction.instanceRequestAction(WOAdminAction.java:96) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at com.webobjects.appserver.WODirectAction.performActionNamed(WODirectAction.java:144) at com.webobjects.appserver._private.WOActionRequestHandler._handleRequest(WOActionRequestHandler.java:259) I’ve just seen this as well, though I can’t reliably reproduce it. In any case, modulo some line number changes, this is the code: public void stop() { if (_queueThread != null && _queueThread.isAlive()) { _running = false; _queueThread.interrupt(); } else { throw new IllegalStateException("Attempted to stop the " + getClass().getSimpleName() + " when it wasn't already running"); } } Unfortunately the original author is long gone, but I’m not seeing the rationale for throwing an exception here. This is being called when ERXApplication.ApplicationWillTerminateNotification is posted. If _queueThread is null or not alive, couldn’t we just do nothing and log it? There’s nothing catching this exception, and it goes on to prevent termination, as Ted notes. Does anyone have any thoughts on this? -- Paul Hoadley http://logicsquad.net/ _______________________________________________ Do not post admin requests to the list. They will be ignored.
