Ales,
See:

Just FYI:
It doesn't have any relation to HA or Full profile, I caught it in WebProfile too
(standalone.xml).
Also my statement about relation to quick shutdown after finished start is out-dated, it
is definitely not true.
Anyway - I didn't see it in ER1 yet.

Ah, OK, should have checked JIRA first ...
Is it easily reproducable for you?
Not really, just saw it once -- before I sent the email.
And I do run AS7 a lot these days, hence it's probably gonna be hard to find the real
cause.
btw: my "capedwarf" branch is merged with AS7.1.0.Final tag.

Yea, this is a hard one to reproduce. After inspecting the JacORB code I
think I know where the problem is. I'll change the CorbaPOAService so
that only the RootPOA is destroyed (it will destroy all child POAs in
the process).
Calling destroy on all POAs as we are doing now can lead to a race
condition where a child POA can remove itself from the parent POA while
the parent POA is iterating through its children to destroy them.
Iterating through an Enumeration, like JacORB does in this case, is not
fail fast and the above scenario will lead to the NPE that is randomly seen.
Cheers,
Stefan

How is
that upstream release with (almost all of) our patches incorporated?
I guess this one can also e included...

I started seeing this from time to time back in December :-/ but I don't
have anything deterministically reproducible.
