We don't have root/sudo root access to upgrade or install libs in the slave, so I've modified the build to download and compile the latest OpenSSL version
Argh, I should have explained the issue with the Javadocs build, which had the same problem (amongst other things). An alternative solution is to tag the job with "lxc-fedora25"; then it will run on a newer machine.
Let me try that quickly on the jobs you fixed. Thanks for taking care of those, Ignasi! ap
