I am still debugging a $%$^%$% issue where Spring tries to close a=20
connection and JBoss says it is unknown.

Clearing transaction synchronization

My feeling is that this is a JBoss bug of some sort though. It was worse=20
in 3.2.2RC3, happeing in a number of places. When I moved to 3.2.3, it=20
only happened in one spot, among a bunch of code that is essentially=20
similar. My feeling is that it's some sort of race condition in the=20
JBoss transaction code. Certainly, if I look at the wrapped connection=20
and the actual connection, right before we call close() on it, it says=20
it is not closed. Then the close() call causes the error to show up in=20
the log...

Weird stuff...
