   83 | InstanceKlass** klass_addr = VMClassses::klass_addr_at(klass_id);
      | ^~~~~~~~~~

   84 | Klass* klass = VMClassses::klass_at(klass_id);
      | ^~~~~~~~~~
This is an obvious typo in "VMClassses", it should actually be "vmClasses".

This readily manifests in current GH Action runs. It would have been caught by #2246 PR, if GHA were enabled, @iklam.

Additional testing:
 - [x] Linux s390x hotspot cross-compile
 - [x] Linux ppc64le hotspot cross-compile
