########## flink-core/src/main/java/org/apache/flink/api/common/serialization/SerializerConfigImpl.java: ########## @@ -356,6 +356,9 @@ public void configure(ReadableConfig configuration, ClassLoader classLoader) { configuration .getOptional(PipelineOptions.FORCE_KRYO_AVRO) .ifPresent(this::setForceKryoAvro); + configuration + .getOptional(PipelineOptions.BUILT_IN_COLLECTION_TYPES) + .ifPresent(TypeExtractor::setBuiltInCollectionTypesEnabled); Review Comment: You are right, the TypeExtractor is a static util class. However, it is only used when compiling the job, which is done on the client side for Session mode, where only one job is executed at a time. Since migrating TypeExtractor to an instance class is not an easy job, we might better implement it in this way first, and try migrating it to an instance class for proper parameterization later.
