-----------------------------------
Summary: ProtobufMarshaller throws ClassCastException when marshalling CDI
proxied KieSession.
Key: DROOLS-278
URL: https://issues.jboss.org/browse/DROOLS-278
Project: Drools
Issue Type: Bug
Security Level: Public (Everyone can see)
Affects Versions: 6.0.0.CR3
Environment: Mac OS-X 1.0.8.5, Hotspot 1.7.0_40
Reporter: Duncan Doyle
Assignee: Mark Proctor
I have a CDI (Weld) @Producer which produces a KieSession. The KieSession is therefore
proxied by a CDI/Weld proxy. When I try to marshall such a KieSession object, the
ProtobufMarshaller throws the following ClassCastException:
01:21:07.505 [main] ERROR o.j.d.b.c.CdiSessionPersistenceTest - Error saving KieSession.
java.lang.ClassCastException:
org.jboss.weld.proxies.CommandExecutor$EntryPoint$KieRuntime$KieRuntimeEventManager$KieSession$ProcessEventManager$ProcessRuntime$RuleRuntime$StatefulProcessSession$StatefulRuleSession$WorkingMemoryEventManager$761192450$Proxy$_$$_WeldClientProxy
cannot be cast to org.drools.core.impl.StatefulKnowledgeSessionImpl

I've created a reproducer which shows the behaviour:

Just run 'mvn clean test' in the project.
