Java 19 builds #50

Closed FireMasterK closed 1 year ago

FireMasterK commented 1 year ago

Title,

Will these be made available?

Could we have docker images for them too?

AdamBrousseau commented 1 year ago

I don't believe there is a definitive answer on whether OpenJ9 will GA a jdk19 level. The intention and hope is to release it before the April CPU security updates. IBM is currently producing Milestone builds as we work towards GA. If we release a GA we will also create containers on DockerHub and IBM Container Registry.

Here is the OpenJ9 Milestone plan for the release https://github.com/eclipse-openj9/openj9/milestone/35

I'm not sure I can say much more than that but one of the dev leads may chime in.

Interesting, I believe Java 19's support period will also end in less than 2 weeks, unless it doesn't apply to OpenJ9.

This is according to https://endoflife.date/java

Yes, jdk19 eol aligns with the jdk20 release date as it is a short term release. OpenJ9 (likely) won't produce any 19 releases after 19.0.2 is GA. I believe there is still value in OpenJ9 and IBM Semeru delivering jdk19 after March 21. I'm not sure what commercial support offerings there are for short term releases (cc @mstoodle ).

We would not extend commercial support beyond the usual dates without significant demand which I don't think would materialize even for Java 19, but I think there's value in producing the binary release for 19 so people have something to evaluate, so long as it doesn't interfere too much in delivering Java 20 (i.e. I wouldn't want to make Java 20 substantially later just so that we delivered a late Java 19), in particular because the later 20 releases, the more impact we're likely to see in Java 21 release date. That's the trade-off and "snowball" issues we're trying to manage now.

Speaking for myself, I'm much more interested in Java 20 at this point, but more generally I'm hoping that IBM establishes a process that allows Semeru to be GA'd consistently close to the upstream OpenJDK GA date. Ideally that would include the container images (Ubuntu and UBI), but at least if the download is available I can roll my own image.

We released 19.0.2 earlier this week. Docker images should be up next week on IBM Container Registry and DockerHub. https://developer.ibm.com/languages/java/semeru-runtimes/downloads/?version=19
