  If persistence.xml has a property element with a name that
  contains leading or trailing whitespace, the product throws a
  NullPointerException, and the application fails to start.
  

Problem conclusion

• The JPA container internally stores all properties in a map.
  While processing properties later, it iterated over all property
  names and indexed the map and used the value, but leading and
  trailing whitespace was removed from the property name, so the
  value could not be accessed.  The product was changed to iterate
  over key and value pairs in the map rather than iterating over
  property names with leading and trailing whitespace already
  removed.
  
  The fix for this APAR is currently targeted for inclusion in fix
  pack 8.5.5.4.  Please refer to the Recommended Updates page for
