But it fails the following two requirements for an equals implementation: -

  | # It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.

The following requirement from hashCode will also not be met: -

Basically you can not put different principal implementation in a HashMap and expect consistent behaviour.
