[rules-users] Drools causes switch(enum e) to break?

So I have a really weird problem and I think it could be relate-able to Drools, or maybe not but maybe some people here have seen it before. I have a simple enum called 'RuleTypes' which is defined in its own file. I have somewhere in my class a switch statement where I use the enum like this: (The method is not finished, but its enough to show the problem) public IResult EvaluateRule(Object obj, RuleType type) { //TODO switch(type) { case Discount : TripRequest lr = (TripRequest) obj; _Session.execute(lr); return lr.getResult(); case Content: break; case None: break; default: break; } return null; } But I get an error saying 'Cannot switch on a value of type RuleType. Only convertible int values or enum variables are permitted'. While RuleType an enum is 100% sure. Yet if I make a new project (with no drools libraries), make the same RuleType enum in its own file and have an empty class doing: public Test(RuleType type) { switch(type) { case Discount : break; case Content: break; case None: break; default: break; } } There are no compiler errors. Anyone know here what could possibly happen? The only thing I could find was a possible Eclipse bug but that one had a fix that does not work for me ( https://bugs.eclipse.org/bugs/show_bug.cgi?id=413368 ). -- View this message in context: http://drools.46999.n3.nabble.com/Drools-causes-switch-enum-e-to-break-tp...
