Class Found Exception:

That error message is different. It looks like there are spaces in the name of the exception. Why is that?

Class Found Exception

Am I glad I never saw that exception before; one of my latest applications has more than 4000 classes running (according to jconsole).

kind regards,

Jos

Why did you create a new account to post that? Couldn't you be upfront about omitting the information the first time round?

We don't like sly behavior here. I'm closing this thread and banning both accounts: Ashwin for a week and thrasher permanently.
