[11u]: 8048556: Unnecessary GCLocker-initiated young GCs

[John Cuthbertson]

Hi Roman,

I was going to contribute a back port patch for this bug for jdk8-dev but it looks like you’ve already done the back port. So I can review if you wish. I think I’m still listed as a reviewer for some projects. I actually changed Kim’s test to to use GC MXBeans to get the eden memory use before GC, write it out in a standard form, and check that the eden use was above 40%.
