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

[Leonard93]

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 (
