Thanks, this looks good.

But I have my usual nitpicky comments

  376     // sets the console echo on/off
  377     private static native boolean echo(boolean on) throws IOException;

I would document the return value.
  @returnsthe previous console echo on/off status

  314                 boolean echoWasOn = true;
I much prefer leaving it blank (in Java, not C !)

boolean echoWasOn;

relying on definite assignment in Java for safety.
