After upgrading Jenkins from 2.58 to 2.59 I got the following trace in the log (the plugin still seems to be working though):

olivergondza Is this just a dependency issue from the pom.xml file?

If that is all this is then I would be happy to make those changes but I am not 100% sure with that stacktrace

I can reproduce this issue with Jenkins 2.70 on an up-to-date Arch Linux host. My procedure for reproducing this issue is:

Completely reset Jenkins. Blow away all plugins, job configurations, etc.
Start Jenkins and proceed through the first-time set-up procedure. Create a user, and don't install any of the suggested plug-ins.
Install the cobertura plug-in, and restart Jenkins.

My procedure for completely resetting Jenkins in step 1 is:

systemctl stop jenkins
rm -rf /var/lib/jenkins/*
systemctl start jenkin

My procedure for installing the cobertura plug-in in step 3 is:

ssh localhost install-plugin cobertura
ssh localhost safe-restart

Here's the plugins that are installed after step 3:

$ ssh localhost list-plugins
Warning: Permanently added '[localhost]:30354' (RSA) to the list of known hosts.
bouncycastle-api bouncycastle API Plugin 2.16.1
cobertura Cobertura Plugin 1.10

Here's some log output from after step 3:

I see a similar error in a more full-blown deployment, too, with dozens of plug-ins installed. In a more full-blown deployment, disabling the cobertura plugin prevents this error from being logged.
