hi,<br>
<br>
We are using Drools 4.0.7 in a web application deployed in WebSphere 6.1.<br>
Occasionally, we have rule engine failure caused by RuntimeDroolsException<br>
(whose root cause is shown as ClassCastException) when firing rules. Other<br>
times, the rules are executing without errors. Here is the stack trace of<br>
the exception. What are the possible reasons?<br>
<br>
Thanks,<br>
