Obviously, Kawa should not throw ArrayIndexOutOfBoundsException,

I fixed Kawa to print an error message in this case, rather than
throwing ArrayIndexOutOfBoundsException.

The message isn't as helpful as I'd like. One complication is that
pattern variable names aren't available at macro-expansion time.
This could be changed, but it isn't a priority right now.
