By using the firebug add-on in firefox, we can see that there are unnecessary http requests for the static resources of the analysis plugins.
For example, for every display of https://builds.apache.org/job/Ant_Nightly/
there are unnecessary http requests for findbugs-24x24.png and tasks-24x24.png (see "project page.png"). The browser should know that this is useless to ask.
And for every display of https://builds.apache.org/job/Ant_Nightly/tasks
there are unnecessary http requests for utilities.js, dispatcher-min.js, findbugs-24x24.png, tasks-24x24.png, spinner.gif and clearpixel.gif (see "tasks page.png").
According to https://groups.google.com/forum/#!msg/jenkinsci-dev/qQf7Tuu6uiw/_WO7OBj_LIkJ
this can be fixed by using "Jenkins.getResourcePath()" or $
Firebug can be used locally to check the changes.
