Description
JDK-8210100 only adds parallel weak oops processing to Young GC, but not Full GC.
In `psParallelCompact.cpp`:
maybe the required change is just from
```
WeakProcessor::weak_oops_do(is_alive_closure(), &do_nothing_cl);
```
to
```
WeakProcessor::weak_oops_do(ParallelScavengeHeap::heap()->workers(),
is_alive_closure(), &do_nothing_cl, 1);
```
PS: make sure the logging looks OK.
