Consistent Exception when using Composite Destinations

[Simon Wistow <si...@thegestalt.org>]

Since switching to using non-transactional Composite Destinations I've 
started seeing this Exception every so often ...

I noticed that there's a post to this list from back in April that notes 
this may be a regression in Spooling. Is there a later version I should 
be running?

This is Java 1.5.0_07-b03 and ActiveMQ 4.0.1

Thanks,
