Class cast exception on stateful ejb

Question

For some strange reason I am getting the following exception.

2011-02-08 09:53:30,667 ERROR [STDERR] (QuartzScheduler_Worker-9) java.lang.ClassCastException: org.javassist.tmp.java.lang.Object_$$_javassist_seam_7 cannot be cast to no.kommuneforlaget.fagsystem.saksapp.service.report.SystemlogListener

I know it shouldn't be a class cast exception because its the correct class.

The code is:

SystemlogListener systemlogListener = (SystemlogListener) Component.getInstance("systemlogListener", ScopeType.SESSION, true);

And the class is

@Name("systemlogListener")
@Scope(ScopeType.SESSION)
@AutoCreate
@Stateful
@TransactionManagement(TransactionManagementType.CONTAINER) //default
@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
public class SystemlogListener implements SystemlogListenerLocal, Serializable {

Can anyone spot the mistake I have made?
