Bug? DWT.Verify events' text field corrupt?

e.text.length, e.text));
	};
}

void main() {
	Display display = Display.getDefault();
	Shell shell = new Shell(display);

	Text input = new Text(shell, DWT.BORDER);
	input.handleEvent(null, DWT.Verify, onTextInput);

	input.pack();
	shell.pack();
	shell.open();

	while (!shell.isDisposed())

	display.dispose();

Whenever I paste something into the text box in the above program, the message
box comes up with strange results.

For instance, pasting "asdf", I get "Got string of length 11: XXX asdf". The
latter "XXX" doesn't show up at all, and the string should be of length 4, not 11.

Making the delegate write to a file I see the whole string, and find that it's
full of strange characters that shouldn't be there - memory not actually
belonging to the array, but apparently taken because the length is incorrect.

Wrapping a toString() call around e.text seems to make it work, but why does
this occur in the first place? Is the type of e.text really char[] in this case?
And/or is there just a bug somewhere causing the length to be wrong?
