 Is it equivalent to JDK 11 Writer#nullWriter?

If so I'm -0, not a blocker, but I have on a Python project for about 1 year, catching up
with the language and libraries, and lost track of JVM release dates, EOL. But I think Java
11 will be LTS, and maybe others will update to it quickly?

But if it's not doing the same as Writer#nullWriter, +0 (I don't have a use case for it, but
sounds OK/useful to others)

 Hi All:

We have a handy NullOutputStream.

I'd like to add a convenience NullPrintStream, which would dead simple:

 * This PrintStream writes all data to the famous <b>/dev/null</b>.
 * <p>
 * This print stream has no destination (file/socket etc.) and all bytes
written to it are ignored and lost.
 * </p>
 * @since 2.7
public class NullPrintStream extends PrintStream {

    public static final NullPrintStream NULL_PRINT_STREAM = new

    public NullPrintStream() {
        super(new NullOutputStream());


Any objections?
