Re: JDK 9 RFR of JDK-8122944: perfdata used is seen as too high on sparc zone with jdk1.9 and causes a test failure

Seems reasonable.

Thanks,

Hello,

In certain machine configurations (large SPARC boxes with lots of
threads), the test

     sun/jvmstat/perfdata/PrologSanity/PrologSizeSanityCheck.java

fails because the PerfDataMemorySize buffer gets too close to its limit.
To allow the test to pass on machines like this as well as smaller
boxes, I'd like to just bump its PerfDataMemorySize to 64k from the
default of 32k. The patch to accomplish this is:
