  This is an intermittent issue, org.omg.CORBA.NO_IMPLEMENT is
  thrown at the client side, and In Z/WAS control region
  ClassNotFoundException is logged for the same class on which ORB
  triggered the meta request.  -
  java.lang.ClassNotFoundException : ClassName
  

Local fix

• If possible avoid the meta request by ensuring that both the
  server and the client have the same version of class.
  

Problem summary

• The problem is caused because meta request was being sent to
  Z/WAS control region instead of the servant region.
  

Problem conclusion

• ORB has been updated to ensure that meta requests are sent to
  the servant region in Z/WAS.
