Summary: MDB pool size is not bounded -- Is the max size being read?
Initial Comment:
I don't really want to create 100 MDB for my
application, so I changed the standardjboss.xml
configuration (like I did in 3.2):

This doesn't seem to work and I end up with hundreds of
threads (and eventually run out of sockets...)
Actually setting this number to -1 or something else
doesn't create any error...
I end up with this in the logs:

We have a rather bizare notion of MaximumSize in that it is a
soft limit that will be exceeded if demand warrents it. I have
restored the strictMaximumSize notion of 2.4 to 3.0.5 and
3.2.0RC1 so that a configuration like:
<container-pool-conf>
<MaximumSize>5</MaximumSize>
<strictMaximumSize>true</strictMaximumSize>
</container-pool-conf>
means only 5 instances will be created.
