------------------------------------
Summary: 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
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.
