JsonMappingException when trying to instantiate org.springframework.messaging.Message [SPR-16486]

[spring-projects-issues]

Itamar Benjamin opened SPR-16486 and commented

in StreamListener input, when trying to receive a parameterized Message instance (see referenced github gist link), this exception is thrown:
org.springframework.messaging.converter.MessageConversionException: Could not read JSON: Can not construct instance of org.springframework.messaging.Message: abstract types either need to be mapped to concrete types, have custom deserializer, or contain additional type information

this was introduced in spring-messaging:4.3.14.RELEASE, overriding only this dependency to 4.3.13.RELEASE resolves this issues
