Description

============= Spec ========================
public short shortValueExact()
Throws:
ArithmeticException - if this has a nonzero fractional part, or
will not fit in a short.

================ Test =========================
import java.math.BigDecimal;

public class Test {
public static void main(String args[] )

{ BigDecimal.valueOf(0L, -22).shortValueExact(); }

}

================ Output =====================
RI throws java.lang.ArithmeticException: Overflow
Harmony throws nothing, just return 0

Actually BigDecimal.valueOf(0L, -22) equals 0E+22. So Harmony follows
spec and looks absolutely logically.
