Stefan Richter created FLINK-10839: -------------------------------------- Summary: Fix implementation of PojoSerializer.duplicate() w.r.t. subclass serializer Key: FLINK-10839 URL: https://issues.apache.org/jira/browse/FLINK-10839 Project: Flink Issue Type: Bug Components: Type Serialization System Reporter: Stefan Richter Assignee: Stefan Richter Fix For: 1.6.3, 1.7.0
The implementation of {{PojoSerializer.duplicate()}} currently ignores that subclassSerializerCache is a shared resource. We must always return a new instance of the serializer, even if all the nested field serializers are not stateful or else concurrency problems might occur if we have cached subclass serializers. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
