[jira] [Commented] (CLI-296) CommandLineParser does not throw unrecognized exception if option starts with a prefix substring

    [ https://issues.apache.org/jira/browse/CLI-296?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16894789#comment-16894789 ] 

Emmanuel Bourg commented on CLI-296:
------------------------------------

Partial option matching is actually a feature of Commons CLI. If the partial option is unambiguous then it's automatically matched.
