KeyEvent difference between 1.6 and 1.7

[Michael Hall]

I have a CLI type app that sometimes uses CTRL-D to terminate input from standard in.

   	public void keyTyped(KeyEvent kevt) {
   		System.out.println("CmdJConsole: byte " + (byte)kevt.getKeyChar() + " code " + kevt.getKeyCode());
   		int modifiersEx = kevt.getModifiersEx();
        System.out.println("CmdJConsole: modifiers " + modifiersEx);
		if ((byte)kevt.getKeyChar() == (byte)4)
			((CmdIn)imp.getIn()).eod();

With 1.7 I see this here...
CmdJConsole: byte 100 code 0
CmdJConsole: modifiers 128

With 1.6
CmdJConsole: byte 4 code 0
CmdJConsole: modifiers 128

Am I handling this incorrectly and shouldn't expect the 4?
Or is that OK and this should not be different.
