> Set a service attribution "semaphore" to "fail" and try to run it twice in short delay. Since the first one obtains the lock, the second will "fail" and throws out the "SemaphoreFailException" exception which will be catch in ServiceDispatcher.runSync method and triggers the semophore.release within that the NPE occurred because of null lock value.
