JIRA links on changes report are broken

See the sample changes report for an example of what I mean:
http://maven.apache.org/plugins/maven-changes-plugin/changes-report.html

The link to MPJIRA-11 on this page is broken - it points to the following page, which is an error message:
http://jira.codehaus.org/browse/ViewIssue.jspa?key=MPJIRA-11

This appears to be because the issueLinkTemplate has an inappropriate default value:
%URL%/ViewIssue.jspa?key=%ISSUE%
according to http://maven.apache.org/plugins/maven-changes-plugin/changes-report-mojo.html

A default value of of %URL%/%ISSUE% would result in the following link, which does work:
http://jira.codehaus.org/browse/MPJIRA-11
