Answer 1

Permanent Generation. See the java GC tuning guide for more details on the garbage collector.

If I remember correctly, the gen stands for generation, as in a generational garbage collector (that treats younger objects differently than mid-life and "permanent" objects). Principle of locality suggests that recently created objects will be wiped out first.
