I think the hotspot has an optimization and detects that finalize() has no bytecodes and treats the object as not needing finalization. http://hg.openjdk.java.net/jdk10/master/file/7d67bb6b0599/src/hotspot/share/...
// Check if this klass has an empty finalize method (i.e. one with return bytecode only), // in which case we don't have to register objects as finalizable if (!_has_empty_finalizer) { if (_has_finalizer || (super != NULL && super->has_finalizer())) { ik->set_has_finalizer(); } }
