That's unfortunate. The allocate_instance_klass function can easily be changed to also check if class_name == vmSymbols::java_lang_ref_Reference(). But even with that, make images fails.

I wasn't a fan of the REF_REFERENCE name, since it isn't really that descriptive to me, and had hoped to fine a way to just get rid of it instead of finding a better name.
