Hi all,

could you please review this small fix to make java/io/File/GetXSpace.java work again on windows?

the test has been updated to work under cygwin, which includes the following changes:
 - GetXSpace.sh accepts CYGWIN_* as known OS and sets windows path to TMP var
 - uses the same regexp to parse df on windows as on other platforms
 - but uses 'FileSystem' field as Space's name, as opposed to 'MountedOn' on *nix, as on cygwin, MountedOn is cygwin path, while FileSystem is corresponding windows path, and the test expect Space's name to be appropriate path

the patch also includes some small faceliftings:
 - printing out a bit more information to facilitate failure analyses, e.g. df output, exception stack traces
 - usage of try-w/-resources
 - remove of code duplication
 - usage of generics
