RFR(S): 8221262: Cleanups in UnixFileSystem/WinNTFileSystem implementation classes

[Langer, Christoph]

Hi Ivan,

thanks for looking closely.

Yes, maybe that's better. Though it's really just the fallback, one could at least distinguish the two possibilities of IOException in this method...

> Line spacing looks inconsistent.  Please leave an empty line before

Good point, I compared to WinNTFileSystem.java and aligned the line spacing.

Please find the updated webrev here:
