> During start up of JBOSS AS7.0 two GeminiBlueprintExtender Threads deadlock, and services in the JBOSS OSGI container are not started.
> The deadlock appears to be concerned with a Module FallbackLoader, which acquires a lock during a call to loadClassLocal() and then proceeds to use an alternate Module to load the class, if this results in the alternate Module using it's FallbackLoader to load a class or resource, then it must also acquire a lock first. Obviously if two or more threads are attempting this, then a dead lock is possible.
> I will attach the thread dump to this issue as supporting evidence.
