I've never tried this in Java but I've seen this question before. It's a
stty thing. You want to turn off echo. There some fairly readable code in
Term-ReadPassword up on CPAN. It might give you an idea of how to tackle
this.

(temporarily reopen TTY and TTYOUT)
$original_flags & ~(ISIG | ECHO | ICANON);
# -isig: disable the checking of characters agains the special control
# characters INTR, QUIT, SUSP
# -echo: do not echo back every character typed
# -icanon: disable canonical input (ERASE and KILL processing).
