8217850: CompressedClassSpaceSizeInJmapHeap fails after JDK-8217612

[ktakakuri]

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.

The boot JDK for 8u is 8u, so you don't have to replace Long.parseUnsignedLong.

But, in another PR you want to keep the ability to bootstrap with JDK 7, so lgm.
