Request for review (s) - 7098155: Resize young gen at full collections for UseParallelGC

[Tao Mao]

Hi Jon,

Just a comment on comment:

        // Swap the survivor spaces if from_space is empty. The
        // resize_young_gen() called below is normally used after
        // a successful young GC and expects the survivor spaces
        // have been swapped.

->

        // Swap the survivor spaces if from_space is empty. The
        // resize_young_gen() called below is normally used after
        // a successful young GC and swapping of survivor spaces;
        // otherwise, it won't succeed to resize young gen under
        // the current mechanism

Is it clearer?

Thanks.
Tao
