-- Information about the crash:
Application specific details: I'm using UPPAAL 4.1.20. When running a
statistical query, it shows the result in (what I think is a) JOptionPane. If I
run multiple queries together, UPPAAL shows these dialogs in sucession -
acknowleging all of them causes a plasmashell crash.
UPPAAL is closed source, so I can't 100% confirm the mechanism causing the
crash, but give me a few days and I'll try to reproduce it in Java.
The crash can be reproduced sometimes.
