> HashCodeBuilder.reflectionHashCode(Object object) returns always the same result for
any array. The result is 17.
> There is no information in javadoc, that this method works in that way.
> The same situation in previous versions.
> Maybe it is a bug that sould be fixed?
> *Example:*
> {code}
> public class HashCodeBuilderTest {
>     
>     public static void main(String[] args) {
>         
>         System.out.println(HashCodeBuilder.reflectionHashCode(new double[] {1, 1}));
>         System.out.println(HashCodeBuilder.reflectionHashCode(new double[] {2, 2}));
>         System.out.println(HashCodeBuilder.reflectionHashCode(new int[] {3, 3}));
>         System.out.println(HashCodeBuilder.reflectionHashCode(new int[] {4, 4}));
>         System.out.println(HashCodeBuilder.reflectionHashCode(new Long[] {5L, 5L}));
>         System.out.println(HashCodeBuilder.reflectionHashCode(new Double[] {null, null}));
>         System.out.println(HashCodeBuilder.reflectionHashCode(new Object[] {Boolean.FALSE,
1L, null}));
>         
>     }
> }
> {code}
