I have heard from a very discerning person that an exception being thrown (and not caught) in a thread is being propagated to the parent thread. Is that true? I have tried some
Exception propagate upwards in the call-stack.
If you start a new thread from a certain method, it will propagate upwards until it gets to that method.
If that method doesn't catch it, you'll get a runtime error that there's an uncaught exception.
