Sorry for being late to the thread. I am +1 for migrating Jenkins to AdoptOpenJDK by default. We already run significant parts of our infrastructure on AdoptOpenJDK, and so far I have not seen any issues when the HotSpot engine is used. OpenJ9 would be much more tricky taking the historical reports in Jenkins JIRA.
We also have an option to ship OpenJDK and AdoptOpenJDK images in parallel and then move when we feel it works well. Bonus points for switching to Java 11 by default at the same time :D BR, Oleg On Wednesday, October 23, 2019 at 8:08:42 PM UTC+3, Jim Crowley wrote: > > Thanks for the information and invite.
