Local fix

• Add Null Guard
  

Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of IBM WebSphere Application      *
  *                  Server Liberty mpConfig feature             *
  ****************************************************************
  * PROBLEM DESCRIPTION: NullPointerException prevents           *
  *                      application from starting when mpConfig *
  *                      feature is enabled                      *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When the WebSphere Application Server Liberty mpConfig feature
  is enabled, applications may intermittently fail to start and
  the following exception will be seen:
  
  Caused by: java.lang.NullPointerException
  at
  java.util.concurrent.ConcurrentHashMap.putVal(ConcurrentHashMap.
  java:1022)
  at
  java.util.concurrent.ConcurrentHashMap.put(ConcurrentHashMap.jav
  a:1017)
  at
  com.ibm.ws.microprofile.config.sources.SystemConfigSource.getPro
  perties(SystemConfigSource.java:43)
  
  The SystemConfigSource class calls System.getProperties() and
  builds a map from the results.  If System.getProperties()
  returns a null property name, this triggers a
  NullPointerException when the null value is used as a key in a
  ConcurrentHashMap.
  

Problem conclusion

• A simple null check was added to prevent this exception.
  
  The fix for this APAR is currently targeted for inclusion in fix
  pack 18.0.0.4.  Please refer to the Recommended Updates page for
  delivery information:
