Description
There are some flags that can be checked after creating the heap.
For example, PLAB related flags should have between PLAB::min_size() and PLAB::max_size().
And these functions can be measured after creating the heap especially for G1.
Comments
8078904 will be fixed by implementing the PLAB checks as you mention here.
