Tim Fox commented on JBMESSAGING-505:
-------------------------------------

The current solution to this makes a copy of the entire receivers list for every message that is sent through the router.

This is likely to have an adverse effect on performance, especially when there are many receivers.

A better solution should be found to the race condition that does not involve cloning the list.
