Description
The bool _on_stack field is added to constant pool and causes a big gap. There's a flag word that it should be added to. Also MetadataMarkOnStack was excluded by the minimal vm and it's needed if you have methods that have been relocated due to the presence of jsr bytecodes. This isn't just used for redefined classes.
