@Digits.fraction should allow negative values
---------------------------------------------

                 Key: HV-533
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HV-533
             Project: Hibernate Validator
          Issue Type: Bug
          Components: documentation, validators
    Affects Versions: 4.2.0.Final
            Reporter: Devesh Parekh


There are really two bugs here:
1. The documentation for @Digits.fraction does not concretely say what should happen for negative values, but the 1.0 final spec defines the correct behavior on page 133 with the equation @Column.precision = @Digits.integer + @Digits.fraction. This suggests that @Digits.fraction should be negative when @Column.scale is negative.
2. The implementation throws an IllegalArgumentException when @Digits.fraction is negative.
