Description

While reviewing test coverage for FLINK-4705 I have come across that Either only implements partial object reuse (when from and to are both Right). We can implement full object reuse if Left stores a reference to a Right and Right to a Left. These references will be private and will remain null until set by EitherSerializer when copying or deserializing with object reuse.
