Description

According to the JSONP spec, if the json number has non zero fractional part, intValueExact() & longValueExcat() must throw Arithmetic exception: [1], [2]

* java.lang.ArithmeticException - if the number has a nonzero fractional part or if it does not fit in an int
*     java.lang.ArithmeticException - if the number has a non-zero fractional part or if it does not fit in a long

Sample application to reproduce the issue:

public final class Main {
    public static void main(String[] args) {
        JsonArray array = Json.createArrayBuilder()
                .add(12345.6489)
                .build();

        boolean success = false;
        try {
            int value = array
                    .getJsonNumber(0)
                    .intValueExact();
        } catch (ArithmeticException ex) {
            success = true;
        }

        System.out.println("Caught expected exception: " + success);

    }
