It seem with the jboss-marshalling-1.3.0.CR9 upgrade the marshalling api seem broken making at the same time the storeAsBinary configuration unusable.
Consider the following code :

import java.io.Serializable;

public class SerializableObject implements Serializable{

private static final long serialVersionUID = 1L;

private int a;

public SerializableObject()

{ super(); }

public void setA(int a)

{ this.a = a; }

public int getA()

{ return a; }

public static void main(String[] args)

{ byte[] byteBuffer = new GenericJBossMarshaller().objectToByteBuffer(new SerializableObject()); }

}

When run, it will result in :
Caused by: org.infinispan.CacheException: java.io.IOException: Unsupported protocol version 3

Same code was working under Infinispan CR2 revision.
