Summary: Random NullPointerException
Initial Comment:
I occasionally randomly get a nullpointer exception, I think it is a threading
issue since it ussualy happens if I change the molecule I am showing before it
finishes displaying another one. I am using jmol 11.8.9.
Stacktrace:
java.lang.NullPointerException

Message:
I believe this is a bug that goes WAY back to the origins of Jmol. I have
checked in fixes for Jmol 11.9.11 and Jmol 11.8.10. The problem arises from
the repaint renderer thread continuing during the zap command. Possibly...

Message:
hmm, the zap is only being called from createModelSetAndReturnError because
there was an error in the data so that an atom set was not created. It's
trying to clear the (already cleared) model with a zap. That could be the
problem.

I see you are using openStringInline. That's not queued, and it could be
causing the problem. I'll look into that. It would be nice to get this to
be reproducible.
