> The TypeExtractor should first check for interface ResultTypeQueryable before trying to extract the type. This would help in many situations where type erasure causes problems e.g. ([#615|https://github.com/stratosphere/stratosphere/issues/615] | [FLINK-615|https://issues.apache.org/jira/browse/FLINK-615]), ([#842|https://github.com/stratosphere/stratosphere/issues/842] | [FLINK-842|https://issues.apache.org/jira/browse/FLINK-842])
