This might be the wrong forum but..
I've had a look at the jboss 4.2.0 code and as far as I can see the DLQ handler never receives the exception,
it only receives the Message again and has to figure out if it should be dlq'ed or not..
I haven't had a chance to look at Messaging 1.4.0.CR1 source yet, but the release notes says it has fixed a redelivery delay issue.
It doesn't say how, but maybe there is something in the fix that might help..

A MDB is not designed to throw a Application exception, but it is certainly designed to throw a System exception (as any other method).
When using Container managed MDBs, one of the ways to performing a rollback is actually to throw a System exception.
