ClassCastException while calling Java based Sca Service by another one

Question

When a java based sca service is called by another java based sca service and the return
value of the service method is complex type there is allways a ClassCastException like the
following thrown:
weblogic.sca.api.ScaException: java.lang.ClassCastException: de.a.b.c.TransferObj cannot be cast to de.a.b.c.TransferObj
at weblogic.sca.engine.WlsScaService.handleServiceException(WlsScaService.java:145)
at weblogic.sca.engine.WlsScaService.invokeTargetBeanMethod(WlsScaService.java:132)
Same Soa Suite at the same server.
Even if the return type is not used by the lets say "serviceB" and so the type has not to be known
by the "serviceB" like this.
serviceA.anyMethod();
Anyone an idea?
Further findings: Meanwhile we found out that this only happens for local calls. But the decision
to use a remote or a local call is container managed and one of the main benefits of Sca. For remote
calls everything is working fine. A work around solution is to use a Mediator. But by the performance
point of view this is an overkill.
Is there nobody who has the ability to help us? Here quasi at the root?

Delegate definition:
public xyz[] getCount(String accessType,long orgId,Date fromDate,Date toDate)
          return lmsServiceImpl.getCount(accessType,orgId,fromDate,toDate);
Calling code in client:
xyz[] so     =     lmsDel.getCount("group",l,calendar,calendar);
Do i need to add anything to the wsdd file for the xyz bean type??
