Mike, the S is coming from the 5i 0 return value (S for short).  Just
remove the return value and you will get a V (V for void) in the
signature.

But you shouldn't have the STATIC keyword either.  You would only code
STATIC if the Java method had "static" in its header.

(The signature doesn't contain anything about static-ness.)
