Status of recent OpenJDK support

[maximdeclercq]

I was wondering if there is any development towards supporting Java > 11.

Trying to build and run Java 12 or higher, I get something the following error in all cases I tried:

$ kubectl logs pods/papermc-587587b8c5-pvwwh

Hi.

This line:

httpserver failed: Aborted

makes me think it is actually the OSv httpserver module crashing.

Could you please do two things to eliminate the issue?

1. Build and run an image without httpserver and see if it works with java only.
2. Enable verbose output so we can see any issues.

On my Fedora, I am able to run some Java apps on OpenJDK jdk-17.0.5+8 on OSv. Could you please tell me what exact version of OpenJDK you are using java --version?

Closing as I have not heard back. Please ask more questions on https://groups.google.com/g/osv-dev
