Re: [rules-dev] unknown error while parsing

In such cases, the parser may raise a runtime exception like a NPE. To avoid blowing the application using the parser or the Drools IDE, we added a catch all exceptions with the message: "this is a bug, contact the development team" when that happens. This is to direct you, users, to report us what kinds of incorrect syntax make the parser explode. Once found, it is farly easy to fix.
