[jboss-jira] [JBoss JIRA] Closed: (JBRULES-589) WokingMemoryLogger and generics: ClassCastException

[Edson Tirelli (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBRULES-589?page=all ]

Edson Tirelli closed JBRULES-589.
---------------------------------

    Fix Version/s:  4.0.0.MR4
       Resolution: Out of Date

I just tested your sample project against 4.0MR3 and the problem is solved.
As we will release 4.0 final in a few days, we will not solve this in old 3.0.x branch.

If you are a JBoss Rules subscriber and need a backport of the fix to 3.0.x branch, please contact the support team through customer portal.

> I'm using Jboss Rules 3.0.5 and Java 1.5.0_09.
