It's been a few days since this question was asked, and I am
also
interested in the answer. I'm currently using an eval to get around
the problem, but is there any way to check enum equivalence directly
in drools?
I beleive it'll work with primitive enums (int), but not enum classes.
If you tried it and it doesn't work, probably safe to assume it doesn't
support it :)

Thanks,
Kris
