If we go forward with jBPM, I may well look into contributing something to solve this issue; catching the exception doesn't solve the problem, since it's the creation of an exception (rather, the population of its stack trace) that causes slowdown. I'd have to look deeper and see if there's a way to solve the problem without triggering an exception. In any case, I'm not ready to commit to that work at this stage, was just trying to learn if there was an existing way to accomplish what I was looking for in the API that I'd missed. There isn't, so, as I said, no big deal, I'll just catch the exception in my code for now, and consider contributing a patch later.
