With regards to testing this with Spock, you can use @Requires({ jvm.java23Compatible }) but apart from this, is there any other runtime arg that you can test with?

• I would say I have no idea. The GraalVM doc only mentions this one available runtime arg.

• I submitted a new commit to supplement the unit tests, but there is still an awkward problem. It seems that the gradle wrapper 7.4 used by the native-maven-plugin module does not support the JDK 23 runtime. I say this is awkward because I'm testing on Windows and can't set a session-level environment variable GRAALVM_HOME like Ubuntu can.

The one added here is still skipped

I believe that is because the test is annotated with @requires({ jvm.java23Compatible }) (and we are running our dev builds on JDK25).

@linghengqian sorry for the late response. Can you try something like this. You can calculate currently used version like this:

def getCurrentJDKVersion() {
        return NativeImageUtils.getMajorJDKVersion(GraalVMSupport.getGraalVMHomeVersionString())
}

and then your requires annotation should be something like

@Requires({ getCurrentJDKVersion() >= 23 })

@linghengqian thanks for your contribution. From testing side it looks okay now. Since you force pushed commits, original approval from @alvarosanchez is dismissed.

@alvarosanchez can you please re-approve the PR if it is still okay (since I don't know the previous state of PR and there is only one commit in history)
