Make org.springframework.http.MediaType Serializable [SPR-8738]

[spring-projects-issues]

Artem Bilan opened SPR-8738 and commented

Immediately show an example.

1. HttpRequest is received with Spring-integration http:inbound-gateway/ without any mapped-request-headers restrictions.
2. So it applies all HttpHeaders including Accept
3. Then that String parsed with MediaType.parseMediaTypes and resulted ArrayList stored in MessageHeaders
4. So, when I use some external messageStore in nested message-flow

java.io.NotSerializableException: org.springframework.http.MediaType

is throwed.
Total: add imlementation java.io.Serializable to org.springframework.http.MediaType for full compatibility of Spring-Web and Spring-integration-http
