I think this mechanism might be useful as a slightly more efficient way 
of determining the OS, comparing to reading "os.name" property.
However, grep found only 8 occurrences of "os.name" usage in 
src/java.base, so I guess it wouldn't make much difference.

In this particular case, it seems to be easier to just introduce another 
helper class, which has only two realizations: for all Unixes, including 
MacOS and for Windows.
I named it ClassLoaderHelper2, and I'm open for a better name for it.

Would you please take a look at the updated webrev?
