[rules-users] Exception handling policy

Hello, I have got a question about Exception handling policy in Drools 5.0. My issue is a case where a client application triggered rule execution on the server, which was throwing a ConsequenceException. The client, not having drools libs in its classpath, then had a ClassNotFoundException. I would therefore want to catch the ConsequenceException on the server and throw an Exception with its cause. I am not sure however if ConsequenceException.getCause() would always yield a non-drools Exception or if that might be another drools type. Also, is it always a ConsequenceException that gets thrown from a session or can there be other Exception types? Thanks, Gerret
