> We are running into a complex production rule that either doesn't work or generate errors. I debugged and it seems Drools is not using the correct fact for some segments of the rule conditions.  Steps to reproduce
> 1. Build the attached test case
> 2. Run the DroolsDefectTest junit test, it should print value "Worked!" on the output console.
> 3. Modify the rule by remove the commented condition that uses variable b2.
> 4. Run the test again. 
>  Expected result: the rule should output "Worked!" again. 
>  Actual result: failed with error: 
> org.drools.RuntimeDroolsException: org.drools.test.Rule_test_0Eval4Invoker at 68f1f17a : java.lang.NumberFormatException: For input string: "Y"
