SessionContext in Stateful session bean

[edvardasm]

I have session Bean:

@Stateful
public class ContactBean implements Contact, Serializable {
 @Inject private EntityManager manager;
 @Inject private SessionContext ctx;
....
 public void serializeMe() {
 try {
 java.rmi.MarshalledObject mo = new MarshalledObject(this);
 mo.get();
 } catch (IOException ioe) {
 ioe.printStackTrace();
 } catch (ClassNotFoundException cnfe) {
 cnfe.printStackTrace();
 }
 }
}

And then from client I run serializeMe() (trying to serialize) method it thows exception:

Exception in thread "Timer-2"
java.lang.StackOverflowError
at sun.misc.SoftCache.get(SoftCache.java:269)
at java.io.ObjectStreamClass.lookup(ObjectStreamClass.java:244)
at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1029)
....

Then I remove "@Inject private SessionContext ctx;" everything works fine.

What I done wrong?
