[rules-users] Eval0Invoker : java.lang.NullPointerException

[Venkat]

Hi, I am new to Drools and I have read about it and not mastered yet. I have
written some rules and junit to test it. The rules works good and passes the
test if ran individually, but if ranned all at once with one junit test case
with all the test cases in it, it is through this exception.

Please find the stack trace.

I have googled on this and found that, it might not be able to take all the
rules, one by one, and execute it.  As I said I am new to Drools, I am not
able to work on this.

Please help me on this.

Thanks,
Venkat.
