Minor corrections:
- Remove '\' at end-of-line when wrapping long lists of command arguments. Such character makes no sense on Windows ('^' is used there).
I think that readers should be wise enough to unwrap the lines, and unwrapping is easier when you do not have to delete stray '\' characters.
- Add double quotes to Windows command line samples, as %JAVA_HOME% is likely to contain a whitespace character.
