Gary Tully commented on AMQ-1950:
---------------------------------
Hans, ok, I added the code to start a master slave pair and produce 250
messages to StandaloneApp, see attachement. The test works are expected. Are
you happy that this issues is resolved?
The 'surprising' result you mention above (on the 3rd), in what circumstances
does this happen in the standalone app?
I will try some additional values of "the number of concurrent beans (message
listeners) (default 1)" in the next few minutes it hope of reproducing the
problem.
Otherwise, can we consider this issue closed?

> few at a time works fine.
> The test application is a MessageDrivenBean that sends a message to another
> MDB with a temporary reply queue.
