I have the same symptom on Debain Wheezy with jenkins installed directly (not in tomcat)

jenkins 1.447.2+dfsg-2

I am getting the exact same issue here:

Environment:

Ubuntu 12.04
django-jenkins (starting to see a pattern here?? I am also using django-jenkins)

Traceback:

Same on Debian with 1.480.3+dfsg-1~exp1. Did anybody see this when not using the distro packages or OpenJDK? We have another jenkins running the package from jenkins.org which works without problems.

As far as I can see from stack trace, coverage report style seems to be wrong.
Is your project Java project? python(django) project ?

I am getting the same error. This is an example xml file that causes the error for me.

I have even tried removing inner tags, like having no packages, just the coverage tag, but the error stays the same.

Download from http://bacons.ddo.jp/download/cobertura.hpi and check it. If it works, I'll release fixed one.

Yeah, I though it was not working for a couple of days, but after Jenkins restart it started to. So I think the fix is OK

Thanks!

fixed in 1.9.
