lookup problem between ejb inside an ear with Isolation clas

[pako]

I have a problem during the lookup between two ejb when I configure Isolation classloding for the ears

I have configured all ears to be in isolated classloader spaces and using call by value for remote interface.

the configuration file deploy/ear-deployer.xml contains :

 <mbean code="org.jboss.deployment.EARDeployer"
 name="jboss.j2ee:service=EARDeployer">
 <!-- A flag indicating if ear deployments should have their own scoped
 class loader to isolate their classes from other deployments.
 -->
 <attribute name="Isolated">true</attribute>
 <!-- A flag indicating if the ear components should have in VM call
 optimization disabled.
 -->
 <attribute name="CallByValue">true</attribute>
 </mbean>

I have deployed one ear that contains two ejbs : ejbA and ejbB;
the ejbA calls the ejbB in the same way :

 Context initCtx = new InitialContext();
 Context ejbCtx = (Context)initCtx.lookup("java:comp/env/ejb");
 Object objRef = ejbCtx.lookup("MyStatless");
 home = (MyStatlessHome)PortableRemoteObject.narrow(objRef, MyStatlessHome.class);
 MyStatless clientStatless = (MyStatless)home.create();

and I have configured ejb-ref in ejb.jar.xml :

 <ejb-ref >
 <ejb-ref-name>ejb/MyStatless</ejb-ref-name>
 <ejb-ref-type>Session</ejb-ref-type>
 <home>it.csi.oss.clusterejb.interfaces.MyStatlessHome</home>
 <remote>it.csi.oss.clusterejb.interfaces.MyStatless</remote>
 </ejb-ref>

and in jboss.xml :

 <ejb-ref>
 <ejb-ref-name>ejb/MyStatless</ejb-ref-name>
 <jndi-name>jnp://cst001.csi.it:1100/ejb/MyStatlessClient</jndi-name>
 </ejb-ref>

unfortunately I obtain following exception :
