My job is  running an ANT script which contains a JUnit task followed by a junitreport task. The junitreport task is set to generate a no-frames html report, which is then published through the HTML Publisher plugin.
After being published, the report loses all of its pretty CSS formatting, and the javascript which is the part of the html report is not working. Also does not work if I open it from the workspace; only displays correctly when I open it as a local file. 

See attached screenshots (published report, the report shown from the workspace and the report opened as a local file - only the latter is correctly displayed).
The file itself is also attached, to give an example of what the ANT junitreport task typically generates as html.
