Subject [jira] Commented: (FELIX-1325) gogo doesn't report a command not found error unless an argument is supplied
Date Tue, 25 Aug 2009 00:22:59 GMT

    [ https://issues.apache.org/jira/browse/FELIX-1325?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12747159#action_12747159

Derek Baum commented on FELIX-1325:
-----------------------------------

FELIX-1325-2.patch looks good - let's apply it and move on.

It's actually a superset of FELIX-1520.patch, and that's OK too.
