Hi all, I think I fixed the problem. The problem was that on Jenkins the Build Agent didn't have the permission to access the raw sockets and this caused some tests to fail.
In general what I had to do, was to grant some permissions to the executable running the program: sudo setcap cap_net_admin,cap_net_raw+eip /usr/lib/jvm/java-8-oracle/jre/bin/java The main problem was, that I was granting all sorts of permissions, but it turns out to the wrong programs. In the build log I could see which was the Java executable running the build and after setting the permissions to that, all was working nicely. Now I have to think of a way to add this to the checks in the prerequisite checker ...
