HttpMessageNotReadableException when @RequestBody(required=false) [SPR-9942]

[spring-projects-issues]

David Roberts opened SPR-9942 and commented

I've tested #13877 on 3.2M2 and set @RequestBody(required=false), and it is still throwing org.springframework.http.converter.HttpMessageNotReadableException when I send it a null body from a test client. I would expect my body object parameter to be sent through as null, as per the comments on the @RequestBody.required() method.

Any suggestions?
