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(a)jboss.org for priority
support.
Is MVEL upgrade for Drools 4.0.7 available?
-------------------------------------------
Key: JBRULES-2236
URL: https://jira.jboss.org/browse/JBRULES-2236
Project: Drools
Issue Type: Bug
Security Level: Public(Everyone can see)
Affects Versions: 4.0.7
Environment: UNIX
Reporter: Jayanth Seshadri
Assignee: Mark Proctor
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?
