Response media type is not extracted for @RestController annotation

[cc-jhr]

Setup information
hikaku version: 1.1.0
specification converter: -
implementation converter: SpringConverter
build tool and version: gradle 5.2.1
test framework: junit 5.4.0

Describe the bug
Extracting the response media type is done by checking the @ResponseBody annotation. This is fine for @Controller annotation in combination with @ResponseBody. The @RestControllerannotation combines both already. So in this case the response media type couldn't be extracted.

Expected behavior
Media type is extracted for both cases:

• @Controller in combination with @ResponseBody
• @RestController

Code samples:
Can you provide specifications or code snippets?

@Controller
@ResponseBody
open class GetMappingOneMediaTypeIsExtractedCorrectlyController {

    @GetMapping("/todos", produces = [APPLICATION_XML_VALUE])
    fun getAllTodos() = ResponseEntity.status(200).body(GetMappingOneMediaTypeIsExtractedCorrectlyController())
}

@RestController
open class GetMappingOneMediaTypeIsExtractedCorrectlyController {

    @GetMapping("/todos", produces = [APPLICATION_XML_VALUE])
    fun getAllTodos() = ResponseEntity.status(200).body(GetMappingOneMediaTypeIsExtractedCorrectlyController())
}
