Supporting [[hasProperty]] on JavaBeans

I noticed today that we don’t support the „in“ operator on JavaBeans. ScriptRuntime.IN(Object, Object) returns false if the second argument is a generic object (not a ScriptObject or JSObject).

I was wondering if this is an oversight or intentional. If it is the former, how would we implement this? Is this the case for a non-standard Dynalink operation such as HAS?
