Thanks James!  I would say from the behavior I've been seeing that the RA is
indeed ignoring the groupId.

I created 4 consumers on the queue, deleted the outbound MDB, and moved the
message handling logic into the new class.  When I do that, the grouping is
indeed respected and messages arrive at the SOAP endpoint in the intended
order!  Yay.  That's the good news.

The bad news is that we really want to use MDBs.  Any idea when the RA might
become group aware?
