Edson Tirelli resolved JBRULES-2424.
------------------------------------

    Resolution: Done


The problem is triggered in case your fact class/interface has a method that matches the following 3 conditions:

* it is public
* its name starts with "set"
* it has no parameters

That would make the ClassFieldInspector class to raise an exception, making it impossible to create any field accessors for it.

Anyway, it is fixed now on trunk (to be released in M2) and branch 5.0.x. Meanwhile, the possible workaround is to break one of the three conditions above: either make the method non-public, or rename it to not start with "set" or add at least one (dummy) parameter to it.
