I have a maven2 job that builds Hudson main. If i go to the page for displaying status
for a build I see a list of junit failures. If I click on any of failures I get a 404.
For a live example: http://hudson.ramfelt.se/job/Hudson%20main/639/#showFailuresLink

Steps to reproduce
1. Create a maven2 job that builds Hudson main
2. Make sure at least one test fails in a build
3. Go to the status page for the build
4. Click on one of the failed tests

Expected outcome:
Display the junit failure, link: http://hudson.ramfelt.se/job/Hudson%20main/org.jvnet.hudson.main$hudson-test-harness/639/testReport/hudson.slaves/JNLPLauncherTest/testLaunch/

Actual outcome:
Displays a 404, link: http://hudson.ramfelt.se/job/Hudson%20main/639/testReport/hudson.slaves/JNLPLauncherTest/testLaunch
