  ****************************************************************
  When dumping an FFDC to describe an issue related to file
  store (such as a failure to write to disk), a
  NullPointerException may occur which prevents diagnostic
  information from being included in an FFDC.
  
  The NullPointerException is wrapped in an
  InvocationTargetException, and has the following stack:
  java.lang.NullPointerException
    at com.ibm.ws.objectManager.utils.FFDC$Diagnostics.
                                   ffdcDumpDefault(FFDC.java:356)
  

Problem conclusion

• This APAR resolves the issue, to allow file store to correctly
  dump an FFDC to diagnose the underlying issue.
  It does not resolve any underlying issue.
