Swagger Annotations don't show a body example - swagger-2.0

Question

When working with Swagger Annotations it is not possible to create an example for the request body.
Here comes the annotation stuff for the RESTful resource/endpoint:
#POST
#Path("/{carId}/conversation")
#ApiImplicitParams({
#ApiImplicitParam(name = "Authorization", value = "The AppJWT token", paramType = "header", required = true),
#ApiImplicitParam(name = "ON-BEHALF", value = "The ConsumerJWS token", paramType = "header", required = true),
#ApiImplicitParam(name = "v", value = "API version", defaultValue = "3", paramType = "query", required = true)
})
#ManagedAsync
#ApiOperation(value = "bla", notes = "")
#ApiResponses(value = {
#ApiResponse(code = 200, message = "bla", response = CreateBlaResponse.class, responseContainer = "List"),
#ApiResponse(code = 400, message = "The input was invalid, please check.", response = GenericError.class),
#ApiResponse(code = 401, message = "Unauthorized. Are the headers correct?"),
#ApiResponse(code = 429, message = "Too many requests, please try again later", response = CreateConversationResBody.class)
})
public void createConversationBatchPOST(#ApiParam(value = "Car ID the action should apply to", required = true) #PathParam("carId") String carId,
#ApiParam(name = "body", value = "The Json payload", required = true, examples = #Example(value = {#ExampleProperty(value = "{\"name\" : \"James\"}", mediaType = "application/json")}))
#RequestBody String body,
#Suspended final AsyncResponse asyncResponse) throws IOException {
//.... implementation
}
Do you have an idea why the annotation in the method signature
#ApiParam(name = "body", value = "The Json payload",
required = true, examples = #Example(value = {#ExampleProperty(value = "{\"name\" : \"James\"}", mediaType = "application/json")}))
#RequestBody String body
doesn't lead to the Json example?
