Github user resmo commented on the pull request: https://github.com/apache/cloudstack/pull/1546#issuecomment-219975396 We use, when ever possible, openjdk as we get support from the distribution. Support for openjdk be it 7 or 8, manually patching oraclejdk is time consuming. RHEL support both openjdk 7 (June 2018) and 8 (October 2020) (see https://access.redhat.com/articles/1299013), to me it would make sense to keep openjdk 8 support in cloudstack. It seems, travis does not support openjdk 8 yet.
