[jira] Commented: (CLI-137) Change of behaviour 1.0 -> 1.1

    [ https://issues.apache.org/jira/browse/CLI-137?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12596277#action_12596277 ]

Henri Yandell commented on CLI-137:
-----------------------------------

It seems that this is a simple backwards compat issue. The default behaviour of Option/OptionBuilder mistakenly changed from hasArgs to hasArg. Now it's there - it's probably best to document this very clearly and mark this as wontfix.
