> FindBugs at rank 8 warns about DelegationToken overriding PasswordToken, but doing so in a way that makes {{a.equals(b)}} possibly not the same result as {{b.equals(a)}} when one of them is a DelegationToken and one of them isn't.
> I see two fixes:
> # ensure that the entirety of what describes DelegationToken are in the bits checked by PasswordToken and don't override it
> # change PasswordToken so that it doesn't consider subclasses to be equal... they must also be exactly PasswordToken
