Swing dies if a thread does

Ruby JRuby
1

Hello all. I’ve noticed that if, in a swing (jruby) app, a thread ever
“raises a backtrace” (say…you hit a button, it hits an exception)
after that point, everything in the app appears broken.

Any pointers/thoughts?
Thanks!

Exception in thread “AWT-EventQueue-0” org.racob.com.ComFailException:
