"Expected feature release number in range of 9 to 12, but got: 8" installing oraclejdk8

Thanks for your response

Doesn’t look like a fix to me if it causes things to break, I think the fix would have been to respect the jdk specified in the .travis.yml. Is there any reason why Xenial should not to support oraclejdk8?

My previous error was due to this which when ahead to cause tests to return 401 Unauthorized rather than expected response. I spent lots of time investigating this issue as you can see in the number of commits made, which lead me to realizing the issue was with Trusty, all I had to do was change to Xenial and the tests passed. Authentication Providers usually come with the OS, but seems the version of Trusty you use is missing some upgrades, because spring couldn’t fine any Authentication Provider and your docs don’t recommend running apt upgrade

The difference between a test failure and a test passing was in changing the dist

Which brings me back to my question/request.

Please how can I ensure/force the use oraclejdk8 on Xenial?
