Right. We already handle bytes right in direct method calls, so
there's no need to enhance jcoerce, just fixing jarray-set will do.

> Beside, Java booleans has the same problem, I have to use (make-immediate-object t :boolean) and (make-immediate-object nil :boolean) to fill method arguments when they need "boolean". Why not let us just use T and NIL?

T works as a boolean, IIRC. With NIL, there's the problem that it's
normally used to mean null rather than false.
