Kohsuke Kawaguchi commented on JENKINS-12446:
---------------------------------------------
I tried this on Tomcat 6 and 7 but couldn't reproduce this. And ditto for "java
-jar jenkins.war" --- it works for me.
Those who are seeing this problem, please report your environment and versions
of the relevant software so that we can diagnose this problem further.
