> TypeAnalyzer MatchError when analyzing BitSet type with Scala API
> -----------------------------------------------------------------
>
> Key: FLINK-1191
> URL: https://issues.apache.org/jira/browse/FLINK-1191
> Project: Flink
> Issue Type: Bug
> Reporter: Till Rohrmann
> Assignee: Aljoscha Krettek
>
> The type analyzer of the ScalaAPI treats BitSet as a ListType. When the
> unapply method of the ListType is called with a BitSet type then it will be
> considered a TraversableType. However, within the TraversableType unapply
> method there is an non-exhaustive pattern matching which fails with BitSet.
> There is also a comment which says "TODO: make sure this works as it should".
> As a result, the user only sees that some implicit evidence parameters of
> type TypeInformation are missing, because they weren't generated. From the
> user perspective, it would be nice to receive a more meaningful error message.
