Não é a toa que o Java diz explicitamente (o final foi negritado por mim):
It is not required that if two objects are unequal according to the java.lang.Object.equals(Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hashtables.
