Problem conclusion

• It was found that a deployed application was actually
  using the eclipse framework shipped with WebSphere Application
  Server. The application makes a call to shutdown part of the
  framework in the middle of the server's lifecycle which leads
  to the null registry and ultimately the NPE.
  
  The WebSphere Application Server code has been updated to
  detect a null extension registry and skip using it when it is
  null.
  
  The fix for this APAR is targeted for inclusion in fix pack
  8.5.5.21 and 9.0.5.9. For more information, see 'Recommended
  Updates for WebSphere Application Server':
