Subject [jira] Commented: (CLI-137) Change of behaviour 1.0 -> 1.1
Date Fri, 13 Jun 2008 14:58:46 GMT

    [ https://issues.apache.org/jira/browse/CLI-137?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12604904#action_12604904
] 

Emmanuel Bourg commented on CLI-137:
------------------------------------

I tried your test Russel, it fails on CLI 1.0. I don't think your example is right, you declare
that -D has an unlimited number of arguments, so there shouldn't be remaining arguments, the
last -D option gets 3 values. Your example would work with hasArg() instead of hasArgs().

With hasArg() the test fails on CLI 1.1, and it works on CLI 1.2 with my patch applied.
