I have no problem with that (Drools 5.1.0), using
             try {
                session.fireAllRules();
            } catch( ConsequenceException e ){
                System.out.println( e.getCause().getMessage() );
            }

The error message you have posted looks like a compile time error?

Thanks,

I tried, but what I got is:

[Error: unable to access property (null parent): throw]
[Near : {... Unknown ....}]
[Line: 1, Column: 0]

instead of getting my message...

Greatings,
tom.
