[jboss-jira] [JBoss JIRA] Closed: (JBRULES-589) WokingMemoryLogger and generics: ClassCastException
[ 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Resolution: Out of Date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.
WokingMemoryLogger and generics: ClassCastException
---------------------------------------------------
Key: JBRULES-589
URL: http://jira.jboss.com/jira/browse/JBRULES-589
Project: JBoss Rules
Issue Type: Bug
Security Level: Public(Everyone can see)
Affects Versions: 3.0.5
Environment: Java 1.5.0_9
Reporter: Francesco Dandrea
Assigned To: Edson Tirelli
Fix For: 4.0.0.MR4
Attachments: BacoJBossRules.zip
I'm using Jboss Rules 3.0.5 and Java 1.5.0_09.
I'm using generics, but I see that I can't have the character < in a Fact in
te drl. This is not a problem, I derived my generic class, and the new derived one is not
a Generic class...
(public class MyClassCiccio extends Ciccio<MyClass>{})
Now, when I execute the application without log it works. But when I instantiate a
WorkingMemoryLogger I have a ClassCastException:
Exception in thread "main" java.lang.ClassCastException:
