             Summary: Refactor InvalidTypesException to be checked
                 Key: FLINK-2693
                 URL: https://issues.apache.org/jira/browse/FLINK-2693
             Project: Flink
          Issue Type: Improvement
          Components: Java API
            Reporter: Chesnay Schepler
            Assignee: Chesnay Schepler
            Priority: 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
