I didn't understand the real problem in here. In the stackoverflow example; there is no getter/setter RegisterUserDTO. When Jackson check the pojo canSerialize, however the object is not serializable for jackson.

new ObjectMapper().canSerialize(RegisterUserDTO.class, causeRef); 

This will return false. So Spring encoder can't find suitable converter to encode your object. So it throws:

Could not write request: no suitable HttpMessageConverter found for request type

I think message is clear.
