> 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?
