Java is too limited when dealing with the Console

[Brunoais]

I also noticed now that this does not allow placing the cursor in 
arbitrary places.

With the same restrictions as jline, I could use javacurses.

Unfortunately, it also requires using extra native libraries to work 
because java does not include such API natively.
