Oh, interesting! ConcurrentModificationException. Yes, (Nico) we might need
to look into that. That means that two independent threads are trying to
update the same Java object and have collided. It would indeed be unique to
Jmol 12.1, I think.
I'll look into it this evening if Nico hasn't tracked it down by then. Nico,
do we need to synchronize that?
