Update Travis config  - TravisCI moved away from containers and uses virtual machines now, therefore the sudo: false property has no influence anymore and has been removed https://blog.travis-ci.com/2018-10-04-combining-linux-infrastructures  - switch from OracleJDK to OpenJDK, as we anyway do not use any closed source libraries  - resolves #76
