It sounds like this problem exists for 2.0 and 1.2. I'd like to get
DT running on 2.0 and debug the problem there which I am happy to do.

I did some more thinking about this and I think that the CME is
related to the connection problem.
I think that a bean is failing to get a connection, so I tries to
destroy itself and release its connections. Then (because of the
initial connection problem) it hits an exception trying to release
its resources, which causes it to try to destroy itself and release
its resources...
So, the iterator is already created further down the stack and
trying to remove an element from it is not permitted - Causing the
concurrent modification exception.
If it were not for the exception being thrown, I think that it
might have actually ended up causing an infinite loop.
Could a flag be set in the context that indicates that the exit is
in progress? Then the exit routine could first check for the flag
and only be allowed to proceed if it is not already in progress
somewhere else in the program stack.
Or, if folk think this might be right (the recursive exiting), what
about just catching the CME and letting the routine fail gracefully?

I did some work over the weekend with little success. I started
using Derby as the DB provider and ran into a set of issues around
connection management (no concurrent modification exceptions). In
JDBC mode things ran fine. In Session Direct Mode I experienced
the connection problem. Basically it was complaining about a
queue being full in the exception but I didn't get too involved in
diagnosing that.
Chris, did you run this with Derby or another external DB?
Curious where the fault domain might be for this problem.
I'll continue to work on this, but I want to stay on top of 2.0 as
there are lots of things to chase down wrt to dependencies so I
can't commit a lot of time to diagnosing this problem. Chris,
what's your ability to work on this?
