a "negative" bug - Arrays.fill() is not throwing expected index exceptions IllegalArgumentException and ArrayIndexOutOfBoundsException - in this example with boolean, but fails with all types:

gistfile1.txt

boolean[] b3 = new boolean[2];
try {
	Arrays.fill(b3, 2, 1, false);
	Window.alert("error 1 - IllegalArgumentException expected");
} catch (IllegalArgumentException e) {
}
try {
	Arrays.fill(b3, -1, 1, false);
	Window.alert("error 1 - ArrayIndexOutOfBoundsException expected");
} catch (ArrayIndexOutOfBoundsException e) {
}
