[jira] [Commented] (CLI-317) NullPointerException thrown by CommandLineParser.parse()

["Gary D. Gregory (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CLI-317?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17681310#comment-17681310 ] 

Gary D. Gregory commented on CLI-317:
-------------------------------------

Hello [~PhBastiani] 

Thank you for your report.

The most expedient way to move this forward and avoid confusion would be to create a standalone test method or class anyone can paste in the git master code base. To this effect, please attach a patch/diff or create a PR on GitHub for a failing test.

TY
