Description

At least in Ubuntu Bionic, APT has to download 125MB of packages installing openJDK. Sometime fails in Travis because the 10 minutes timeout. Should this source repositories be replaced by faster ones?

Steps to Reproduce

1. Execute Travis Build
2. See what happens with openJDK builds in Ubuntu Xenial/Bionic

Expected behavior: Pass travis build (at least install openJDK packages)

Actual behavior: Sometimes fails because 10 minutes timeout

Reproduces how often: ~75%
