Here's email from David Jencks:

"I think this will be OK. Let's apply it and see if anything breaks: I
can't think of anything at the moment. I'd like to know what his jboss
settings are, in particular if he is using cache-by-transaction (if I
remember the parameter correctly). I don't understand at the moment
why cleanup would be called with an active transaction, unless there is
a large bug in jboss... but I haven't looked at the jboss code for a
long time."

I will add your fix to the driver.

Thanks!
