Yes, they are discard-able, as in they *can be* discarded once we tested that particular version/mutation of the class. I was/am just worried if the Garbage Collector won't go postal on me if I modify the class whose instance it's trying to collect.

Yes, but from what I understood an agent can also modify the VM's classes - so the idea was to exploit that (eh, "exploit" has a bad sound to it ;)) and modify the VM so that it does include the functionality we need. Does this idea seem reasonable to you? Of course, it would be hard to maintain such "patches", but it would take the burden of installing a custom VM from the users.

Thanks again for your help and best regards,
