You're right. Will refactor the public access to the fields and include the
field in the `equals` and `hashCode` calculation.
> Add abstract equals, hashCode and toString methods to TypeInformation

> Key: FLINK-2637
> URL: https://issues.apache.org/jira/browse/FLINK-2637
> Project: Flink
> Issue Type: Improvement
> Components: Core
> Affects Versions: 0.9, 0.10
> Reporter: Fabian Hueske
> Assignee: Till Rohrmann
> Labels: starter
> Fix For: 0.10
>
>
> Flink expects that implementations of {{TypeInformation}} have valid
> implementations of {{hashCode}} and {{equals}}. However, the API does not
> enforce to implement these methods. Hence, this is a common origin for bugs
> such as for example FLINK-2633.
> This can be avoided by adding abstract {{hashCode}} and {{equals}} methods to
> TypeInformation. An abstract {{toString}} method could also be added.
> This change will brake the API and require to fix a couple of broken
> {{TypeInformation}} implementations.
