    Description

      A MVEL failure causes Drools exceptions in some circumstances:

      Caused by: java.lang.NoClassDefFoundError: org/acme/insurance/Policy

      This issue was fixed in MVEL: http://jira.codehaus.org/browse/MVEL-213
      Is necessary update the mvel library to fix this issue in Drools.

      Although the case related https://issues.jboss.org/browse/JBRULES-2253 mentions that the failure occurs in Sun JVM, I realized tests and the same occurs with IBM JVM. A MVEL updates, fixes the issue it to both. (I tested changing mvel 2.0.10 to 2.0.19).
