ahh...
Now that is impressive in JBoss. "Being able to turn off all copying for a
particular bean." I have not seen this control in other App servers. In
other app server it seems to be automatic and container controlled (ie you
don't get a choice)
Tell me Rickard, do you have any benchmarks of JBoss vs Orion for speed
optimization (official or unofficial) ...

jBoss will not detect this, and I hope noone else does it either. The
thing is that we have no way of knowing that your object is immutable,
even if you only have get-methods. Only having get-methods is not an
insurance that the object is immutable.

In your case I would recommend turning off call copying for that bean in
jBoss. This is done by changing the container configuration that the
bean uses. If you have several beans with the same pattern I would
recommend making one config. that all those beans uses.
