    [ https://issues.apache.org/jira/browse/BEAM-7956?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16905319#comment-16905319 ] 

Neville Li commented on BEAM-7956:
----------------------------------

Actually this might be due to how scala handles primitive types and boxing. I'll investigate more.

>             Project: Beam
>          Issue Type: Bug
>          Components: sdk-java-core
>    Affects Versions: 2.14.0
>            Reporter: Neville Li
>            Priority: Trivial

> Comparing {{Float}} and {{Double}} {{NaN}} values always yields {{false}}, even though they serialize consistently to the same byte array.
> {{FloatCoder}} and {{DoubleCoder}} override {{consistentWithEquals}} to {{true}} but doesn't override {{structuralValue}} which return the orignal {{NaN}} and fails comparison.
> This trips {{MutationDetectors}} in tests.
