Looks fine.

agent/src/share/classes/sun/jvm/hotspot/utilities/PlatformInfo.java mentions "Darwin", not sure why.
Also looks for "FreeBSD" "NetBSD"  and "OpenBSD"
But the rest of the jdk doesn't. Just seems strange to me to be looking for values of the Java property "os.name" that
we don't appear to support.

Again, looks fine.

Also see a "Darwin" in src/solaris/classes/sun/nio/fs/DefaultFileSystemProvider.java:
osname.equals("Darwin")
I don't think it will ever say "Darwin" will it? Not your change, I'm just curious.
And if it ever did say "Darwin", I doubt any of the other files that don't look for "Darwin" would work anyway.

Looks fine.

Just my comments on Darwin, but don't consider that a hold up on the changes.
