[jira] [Created] (NIFI-1632) ExtractText throws NullPointerException if Regular Expression has optional Capturing Group that is not present

Mark Payne created NIFI-1632:

             Summary: ExtractText throws NullPointerException if Regular Expression has optional Capturing Group that is not present
                 Key: NIFI-1632
                 URL: https://issues.apache.org/jira/browse/NIFI-1632
             Project: Apache NiFi
          Issue Type: Bug
            Reporter: Mark Payne


If we use ExtractText and configure it with a regular expression that contains a Capturing Group that is "optional" (ends with a ?), and the regex matches some content where the capturing group is not present, then it will throw a NullPointerException
