post_initialize() is a virtual function of CollectedHeap. EpsilonGC doesn't have a particular reason to override it.
Its implementation just calls the base's post_initialize().
void EpsilonHeap::post_initialize() {
CollectedHeap::post_initialize();
}
```
In universe_post_init(), HotSpot invokes post_initialize() via vtable.
Universe::heap()->post_initialize();
By deleting it, HotSpot still needs a call via vtable, but it will jump to CollectedHeap::post_initialize() directly.
