The fix for 7041789 corrected the meaning of is_scavengable to really mean what it says. Unfortunately there were some places that were really using the change as a proxy for !is_perm. in particular in ciObject::can_be_constant and should_be_constant we will now embed constants that we didn't used as long as they are in tenured. The code should be changed from !is_scavengable to is_perm.
