Work Description: kanterov opened a new pull request #6862: [BEAM-5866]
Override structuralValue in ListCoder and MapCoder
URL: https://github.com/apache/beam/pull/6862
- use underlying coders in `consistentWithEquals`
- allocate objects if needed instead of relying on serialization in
`structruralValue`
