GraalVM 22.3.0 with Java 19 about bellsoft-liberica

[dmikusa]

Again, we cannot add this until it's released by Bellsoft. They don't have Java 19 support yet, so we cannot add it. As soon as they do, we'll add it.

We should be able to add this for GraalVM Buildpack though. Give us a few days to get that updated and released, you can then use these instructions to use GraalVM instead of Bellsoft NIK.

A couple of notes here:

1. According to our vendor Bellsoft, they are not going to support Java 19 in NIK. It goes out of support in Jan 2023, so it's not really enough time. They are contemplating support for Java 20, and will definitely support Java 21 which is the next LTS. Their general strategy is to support the LTS versions, but they may support some non-LTS versions as well.
2. GraalVM has experimental support for Java 19, so I added this into the GraalVM buildpack. You can use that if you want to try out Java 19.

To build with GraalVM, see these instructions.

It's basically like this though:

pb my-cool-app -b paketo-buildpacks/graalvm -b urn:cnb:builder:paketo-buildpacks/java -e BP_NATIVE_IMAGE=true -e BP_JVM_VERSION=19

Or set the buildpack list in build.gradle or pom.xml if you're using the Spring Boot Gradle/Maven build tools.

This is an upstream limitation, Bellsoft doesn't have NIK available for Java 19 at the moment. If/when they make it available, we'll add it. For the time being, you'd need to stick with Java 11 or 17 for building native image apps.

I have the same issue.
the jdk 19 is really important due to the new features such as project loom (which makes us able to use virtual threads), so please consider adding support for it

@dmikusa
thanks for all of ur effort in this matter.
could u please represent a simple pom.xml or build.gradle in gist or somewhere else? it would be very very helpful

See the maven docs, the <buildpacks> tag is what you want. It takes a list of buildpacks. You would use the same two buildpacks I mentioned in my previous note. Example here.
