Currently the only way to print native methods is to use the global `-XX:+PrintAssembly` option. But this prints *all* compiled methods which can be too much if we're just interested in a specific native wrapper. There's no reason to not apply `-XX:CompileCommand` options correctly to native methods as well.

Still not sure how exactly it reproduces for you, but I can now reproduce the issue if I configure with `--with-jvm-variants=core --disable-jvm-feature-zgc --disable-jvm-feature-shenandoahgc --disable-jvm-feature-g1gc --disable-jvm-feature-parallelgc`. Otherwise I'm always running into compilation errors in one of the GC-related files. Maybe you compile on a platform where all these GCs are excluded by default or you excluded them manually?

Either way, I think I found the problem. I'll open a JBS issue and post a PR with a fix in a few minutes.
