org.axonframework.common.lock.DeadlockException
Exception indicating that a deadlock has been detected while a thread was attempting to acquire a lock. This typically happens when a Thread attempts to acquire a lock that is owned by a Thread that is in turn waiting for a lock held by the current thread.
