OutputHandler::run is installed as a MultiStreamCallback into the TaskRunner and it's invoked in the Graph::CallbackToJava() jni method.
In CallbackToJava(), the packets are removed in RemovePacket() calls after the multi stream callback is invoked. The current logic lets the MultiStreamCallback release the packets first and leaves null pointers to RemovePacket() to remove, which may cause the app crash. The fix is to remove the packet release calls in the MultiStreamCallback and always leave the packet release work to RemovePacket().
