[jira] [Created] (FLINK-17882) Don't allow self referencing structured type

Timo Walther created FLINK-17882:
------------------------------------

             Summary: Don't allow self referencing structured type
                 Key: FLINK-17882
                 URL: https://issues.apache.org/jira/browse/FLINK-17882
             Project: Flink
          Issue Type: Sub-task
          Components: Table SQL / API
            Reporter: Timo Walther
            Assignee: Timo Walther


Currently, the logical constraint "A type cannot be defined so that one of its attribute types (transitively) uses itself." is not enforced during extraction and leads to a stack overflow. We should throw a helpful exception instead.
