  ****************************************************************
  * PROBLEM DESCRIPTION: ManagedObjectException occurs on        *
  *                      startup when a noncontextual class is   *
  *                      extended                                *

  * RECOMMENDATION:                                              *
  ****************************************************************
  When a noncontextual class - such as a servlet - is extended the
  managedobject component will look for a bean for that class.
  Since noncontextuals do not have beans it will find the subclass
  and then throw an exception: ManagedObjectException: Managed
  Class {org.example.SuperClass} does not match Bean Class
  {com.example.SubClass}. This exception will be thrown during
  webservices startup, which will essentially take down
  webservices entirely - and no servlet will be available.
  

Problem conclusion

• The managed object component was modified so that it no longer
  attempts to find a bean for a noncontextal class.
  
  The fix for this APAR is currently targeted for inclusion in fix
  pack 19.0.0.8 and liberty 19.0.0.1.  Please refer to the
  Recommended Updates page for delivery information:
  http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
  

Temporary fix

• The Vetoed annotation can be put on the noncontextual class to
  prevent managedobject from attempting to search for a bean for
  that class.
