Hi Martyn, Thanks a lot for this!
It could save us just in time... As soon as I can, I'll try to build artemis from your last commit and make some tests. I'll give you a feedback.

There were two issues which are now fixed as part of: https://github.com/apache/activemq-artemis/pull/1002 I'll get these fixes cherry-picked onto Artemis 1.x stream. I plan on doing a 1.5.3 (with these changes included) within the next couple of days.
