Prateek,
It is difficult to diagnose the problem only by the provided stacktrace.
May I suggest that first thing you do is upgrade the drools version to
4.0.2or if possible
4.0.3 (to be released today)? There are several bug fixes and a few error
message improvements, that hopefully will allow us to narrow the problem.
