RFR(XS) serviceability/sa/jmap-hprof/JMapHProfLargeHeapTest.java failing because expects HPROF JAVA PROFILE 1.0.1 file format

[Erik Gahlin]

Hi,

Could I have a review of a fix for

"8150986: serviceability/sa/jmap-hprof/JMapHProfLargeHeapTest.java 
failing because expects HPROF JAVA PROFILE 1.0.1 file format"
https://bugs.openjdk.java.net/browse/JDK-8150986

It's a test update to accommodate the removal of 1.0.1 HPROF file format 
support that happened with
https://bugs.openjdk.java.net/browse/JDK-8144732

Thanks
Erik
