Jian Zhi commented on JBRULES-2843:
-----------------------------------

This problem exists in regular package as well. In my case I insert a new fact on RHS. If the fact name is same as the fact type I got the object is not an instance of declaring class exception at run time.

The idea solution is to convert the first character of the fact name to lowercase in Guvnor.
