[jdk8u-dev] RFR: 8217850: CompressedClassSpaceSizeInJmapHeap fails after JDK-8217612 [v2]

[Kazuhisa Takakuri]

> Hi all,
> 
> This is a backport of JDK-8217850: CompressedClassSpaceSizeInJmapHeap fails after JDK-8217612  
> The bug reported is reproducible in JDK8, so this follow-up patch for JDK-8217612 is needed.
> 
> The original patch does not apply cleanly. The Long.parseUnsignedLong method was introduced in JDK8, so building with JDK7 as the boot-jdk cannot utilize this method. I have introduced an alternative private method to Long.parseUnsignedLong. This is almost a duplicate of Long.parseUnsignedLong(String s, int radix), but it is necesary to replace compareUnsigned(long x, long y) and NumberFormatException.forInputString(s) with their respective implementations.
> 
> Thank you.
