Aitozi commented on issue #8280: [FLINK-12297]Harden ClosureCleaner to handle the wrapped function URL: https://github.com/apache/flink/pull/8280#issuecomment-501329024 I think the check for primitive type maybe not enough, do you see the last travis ci result <https://api.travis-ci.org/v3/job/544637574/log.txt>, but it seems disappear during the second trigger. No matter the travis result , I think a class below will also run into stack overflow error, right? ``` class A { A fieldA; } ``` Do you think the solution to check the serializability before recursive is not a good idea? I think this can solve the problem because we only have to recursively clean the unserializable fields, WDYT @aljoscha ?
