             Summary: Add test for duplicate() to SerializerTestBase
                 Key: FLINK-10827
                 URL: https://issues.apache.org/jira/browse/FLINK-10827
             Project: Flink
          Issue Type: Test
          Components: Tests
            Reporter: Stefan Richter
            Assignee: Stefan Richter
             Fix For: 1.7.0


In the past, we had many bugs from type serializers that have not properly implemented the {{duplicate()}} method in a proper way. A very common error is to forget about creating a deep copy of some fields that can lead to concurrency problems in the backend.

We should add a test case for that tests duplicated serializer from different threads to expose concurrency problems.
