Hi All,
We are getting the following exceptions when drools is executing some rules.

Could be a bug that has been fixed. No telling without knowing which
version this does. - If it isn't the latest of Drools 5, try 5.6.

Could be a bug that has been fixed in some later version - can someone
confirm this please?
OP is using drools 5.1.1, and should try 5.6.

Similar bugs have been fixed over different versions, but
it's very difficult to tell without some context.
One would need at least the rule that causes the exception,
but a minimal reproducer (rules + facts) would be ideal.
