I was a bit confused by this change but eventually figured it out: 
turning on either of those flags also turns on the other and hence the 
result is the same (as long as we don't explicitly turn off 
UseParallelOldGC).

That kind of begs the question as to what testing coverage we have for 
-XX:+UseParallelGC -XX:-UseParallelOldGC ?

Thanks,
David
