Problem conclusion

• It was found that a deployed application was actually
  using the eclipse framework shipped with IBM WebSphere
  Application Server. The application makes a call to shut down
  part of the framework in the middle of the server's lifecycle
  which leads to the null registry and ultimately the NPE.
  
  The code in the eclipse framework shipped with WebSphere
  Application Server 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
  8.5.5.24 and 9.0.5.15. For more information, see 'Recommended
  Updates for WebSphere Application Server':
