RFR JDK-8151345 : compiler/codecache/jmx/PeakUsageTest.java is failing on jdk9/dev for JPRT -testset hotspot

[Harsha Wardhana B]

Hello,

I forgot to put-in the fix details.

The test was failing because of a race condition caused by the order in 
which MemoryPoolMXBean.getUsage and MemoryPoolMXBean.getPeakUsage was 
invoked. It is possible that intermediate allocations can happen which 
can lead to getUsage > getPeakUsage if getUsage is called after 
getPeakUsage. The correct order would be to capture getUsage and then 
capture getPeakUsage in order to account for intermediate allocations.

Thanks

Harsha
