For complete disclosure, I should note that dead objects in the tenured (old) and permanent generations are looked at (but only during a full GC), since the compaction phase has to figure out where the live ones can be copied to. However, since in nearly all cases, more than 90% of dead objects are in the young generation, few dead objects are examined and the cost is minimal. The "compaction" phase for the young generation (minor GC) actually consists of copying the live objects to a survivor space, which is guaranteed to be empty. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
