Local fix

• Ensure that both server and client use either EJB 2.0 stubs/ties
  of EJB 3.0 stubs/ties.
  

Problem summary

• The ORB code has been modified to detect the incompatibility
  between EJB 2.0 and EJB 3.0 early and throw an exception
  indicative of the same.
  

Problem conclusion

• This APAR will be fixed in the following Java Releases:
     7    SR7       (7.0.7.0)
     6    SR16      (6.0.16.0)
     6 R1 SR8       (6.1.8.0)
     7 R1 SR1       (7.1.1.0)
  .
  A new MARSHAL exception will be logged to indicate the mismatch
  -
  org.omg.CORBA.MARSHAL: Possible incompatibility between Stub and
  Tie at offset fffffffe
