Actually, it's not!
Surprised I didn't think of this before my post, but all you need to do
is overload the methods:
public void onActivate(Integer number1, Integer number2, Integer
number3) {
System.out.println("Activated with " + number1 + " " + number2 +
" " + number3);
}
public void onActivate(Integer number1, Integer number2) {
System.out.println("Activated with " + number1 + " " + number2);
}
You can't make the values limitless, but as you can see from above, you
can definitely make them optional!

That is in fact the only option for now.
Cheers,
