> HE: Class defines equals() and uses Object.hashCode() (HE_EQUALS_USE_HASHCODE)
> This class overrides equals(Object), but does not override hashCode(), and inherits the
implementation of hashCode() from java.lang.Object (which returns the identity hash code,
an arbitrary value assigned to the object by the VM).  Therefore, the class is very likely
to violate the invariant that equal objects must have equal hashcodes.
