Comment 1 Jesse McConnell CLA 2011-07-26 16:25:27 EDT 
Normally I wouldn't comment...but since its from another developer I figured I ought to.

jetty-maven-plugin bugs ought to be opened on the codehaus side....and actually when we find them here we probably ought to open an issue for it on that side and close the issue on the eclipse bugzilla side down with a pointer to the bug over there.
Comment 2 Michael Gorovoy CLA 2011-07-26 19:17:05 EDT 
Whoops, you are absolutely correct, Jesse. I've been looking into another bug in Bugzilla, and opened a new one here on autopilot. I will move it over to JIRA shortly.

Opened JIRA issue for this problem http://jira.codehaus.org/browse/JETTY-1403.
