Description
The attached code generates an NPE when running optaplanner/drools, but that stacktrace doesn't tell me which DRL line is responsible for it.
Stacktrace:
Caused by: java.lang.NullPointerException: null
at ConditionEvaluatoreaa3997683d949e28ce6eaf6feca0ced.evaluate(Unknown Source) <================ No source DRL line
