What you describe is as expected. Topics are a little different w.r.t to expiry as the messages are only persisted on a per consumer basis. If there are no consumers, the messages are discarded so they don't get a chance to expire. If there are durable subscribers the pendingMessageLimitStrategy kicks in and first does message expiry, then does message discarding.
