Why doesn't AtomicReference override equals? [duplicate]

问题

Why are two AtomicIntegers never equal? (9 answers)

The right way to do equals and hashcode of objects held by AtomicReference (3 answers)

Closed 9 months ago.

I started using AtomicReference in Java beans to have the 3state semantic when reading objects from JSON. As I like to have equals and hashCode implementations in my beans I'm wondering why AtomicReference doesn't override equals. The implementation would be trivial (simply delegate to the wrapped value).

Are there any good reasons AtomicReference doesn't override equals and hashCode?!
