Mark Proctor resolved JBRULES-2236.
-----------------------------------

    Resolution: Rejected


There are no plans for us to do any more work on 4.0.7 at the community level. You can try the latest version of mvel, but there is no guarantee that it works. Should you need a patch release for the 4.0.x series of Drools contact sales at jboss.org for priority support.

> We are using Drools 4.0.7 which ships with the mvel-1.3.1-java1.4.jar dependency. At times, we get the following MVEL error (stack trace below) and the Rule Engine skips processing some records. However, during a second run with the same data set we do not get the same error. 
> What we would like to know is if there is a way to upgrade the MVEL jar in Drools 4.0.7?
