> ActiveMQ crashes on subscribing one listener on several topics with a same
> session.
> It crashes on freeing an object in ActiveMQSessionExecutor::wakeup() and
> ActiveMQSessionExecutor::stop().
> Each time that a listener is subscribed to a topic, ActiveMQ stops the
> session. In ActiveMQSessionExecutor::stop(), the shared pointer
> (this->taskRunner) is read but in the same time the shared pointer can be
> modified by ActiveMQSessionExecutor::wakeup() when a message is received from
> the topic. Reading and modifying a shared pointer is not thread safe and
> should be protected by a mutex.
> I've attached a test case and a proposal patch.
