(even accounting for the fact that the retro-compatibility history would be mostly good usually)\r\n- Or maybe this is going to be too hard, enforcing the need to go LTS (with a support contract)?\r\n- Could [Amazon Corretto](https://aws.amazon.com/blogs/opensource/amazon-corretto-no-cost-distribution-openjdk-long-term-support/) be officially supported by JRuby, hence allowing free use of OpenJDK 8 (and later other versions) on a number of OS (Amazon Linux 2, Microsoft Windows, macOS first, and Red Hat Enterprise + Ubuntu in Q1 2019), for more than 6 months in a row?\r\n- Do we need more options in the current JDK test matrix to support this?\r\n- Could https://adoptopenjdk.net help hear too?\r\n\r\nAll in all, anything that will help JRuby users or prospects figure out what they can and cannot do in terms of compatibility \u0026 licensing, especially without an Oracle support contract, would probably help a number of people I guess.\r\n\r\nWell - that's it to get the ball rolling!","author":{"url":"https://github.com/thbar","@type":"Person","name":"thbar"},"datePublished":"2018-12-20T14:46:58.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/14/jruby.github.io/issues/14"}
