> Summary:
> DefaultExchangeRegistry.registerExchange() has a side effect of calling
> messageStore.createExchange.
> This behaviour is unexpected as DefaultQueueRegistry does not do the same for
> queues.
> The problem that this has is that on MessageStore recovery the recovered
> exchanges will be registered. Which after the MessageStore has been recovered
> will cause createExchange to be called. The problem here is that the
> createExchange interface is not designed to cope with duplicates. Something
> that Derby highlights as it throws primary key constraint violation error.
> The solution is to decouple register and create as has been done with queues.
> This has not previously been seen as a) the Derby test profile is not run as
> often and b) the configuration used did not have an additional durable
> exchange defined.
