JME on JDK 16

General Discussion
#1

Hello,

I don’t know how many people have tried, but I figured I would report on running jme on jdk 16.
I was able to compile, run tests, and run a jme app without any issues on jdk 16.
This is not surprising as I did not see any deprecations that should cause us problems, but I figured I would check.

Anyways, for anyone wondering, it does work.

Thanks,
Trevor

I haven’t done any explicit testing per se, but I’m also running my jME application on JDK 16 without issues.

But note that the latest release of Gradle (v6.8.3) doesn’t support any JDK beyond 15.

Yes - I’m using a pre-release Gradle v7 right now, though with the new-ish Java Toolchains feature you can build against a JDK that Gradle itself doesn’t run on:

java {
	toolchain {
		languageVersion = JavaLanguageVersion.of(16)
	}
}

Making a post like this is really useful for Googlers who just want answers.

Note that ReflectionAllocator seems to be broken with JDK 16.

SEVERE: Buffer cannot be destroyed: java.nio.DirectFloatBufferU

Even by adding this JVM arg (which used to solve that on jdk 11+)

"--add-opens=java.base/jdk.internal.ref=ALL-UNNAMED"

you can test it with
