Class org.hibernate.type.AbstractType

public int getHashCode(Object x) {      
        if (x instanceof Object[]){
            int result = 1;
            for (Object element : (Object[]) x)
                result = 31 * result + (element == null ? 0 : getHashCode(element));
            return result;
        }
        return x.hashCode();
    }

            int length = a.length;
