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:
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.

Message:
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.
