So this would mean the agent would be able to get CLFH for _all_ classes, even Object, String, Class etc, that are the very first to be loaded, and potentially instrument the bytes for those classes as well? Of course still following the rules about not introducing any new packages etc at the time, since it would cause the module system verification to fail (yeah, been there, done that). If that is the case, that also seems like a good solution for me, which should still give me access to what I'm looking for. Also, it would basically mean that can_generate_all_class_hook_events would make CLFH work similar to how it does on previous versions. /Michael
