Code review: 7126979 (props) JCK test java_lang/System/GetProperties.java failing [macosx]

[Michael McMahon]

Thanks David. Just found it now (Alan noticed it too). Scott sent his 
webrev yesterday.

It looks like both solutions fix the problem. The difference is that 
Scott's re-initializes
the properties from native code each time System.initProperties() is called.
On the other platforms, we only call it once.

So, do we want Macos to diverge slightly from the other platforms in 
this respect?

My preference is to keep the platforms as similar as possible, 
minimising the changes
with jdk7u ...

- Michael.
