> Refactor InvalidTypesException to be checked
> --------------------------------------------

> Key: FLINK-2693
> URL: https://issues.apache.org/jira/browse/FLINK-2693
> Project: Flink
> Issue Type: Improvement
> Components: API / DataSet
> Reporter: Chesnay Schepler
> Priority: Minor
> Labels: stale-minor
>
> When the TypeExtractor fails, it generally throws an InvalidTypesException.
> This is currently an unchecked exception, although we sometimes recover from
> it, usually by creating a MissingTypeInfo manually.
> Furthermore, the extractor can also throw IllegalArgumentExceptions in some
> cases. Figuring out which exception is thrown under which conditions is
> pretty tricky, causing issues such as FLINK-2557.
> This should be rectified by
> # making InvalidTypesException a checked exception
> # only throwing an InvalidTypesException upon failure
