Critical Description
I've created a factory that uses JAXRSClientFactory to create implementations of my service interface classes.
In the body of each method I create a list of providers to be used by JAXRSClientFactory.create, some of them being ResponseReaderS. Here's an example:
JAXBElementProvider jaxbProvider = new JAXBElementProvider();
JSONProvider jsonProvider = new JSONProvider();
jsonProvider.setDropRootElement(true);
jsonProvider.setSupportUnwrapped(true);
jsonProvider.setConsumeMediaTypes(Service.ContentTypeSummary.PRODUCE_MEDIA_TYPES);
jsonProvider.setProduceMediaTypes(Service.ContentTypeSummary.CONSUME_MEDIA_TYPES);
List<Object> providers = Lists.newArrayList();
providers.add(jaxbProvider);
providers.add(jsonProvider);
providers.add(new ResponseReader(MyListV1.class));
providers.add(new ResponseReader(MyV1.class));
providers.add(new LoggingOutInterceptor(new PrintWriter(System.out)));
providers.add(new LoggingInInterceptor(new PrintWriter(System.out)));
return JAXRSClientFactory.create(
System.getProperty("service.url"),
MyRestfulService.class,
providers,
true);
This particular service has two methods: one that returns a list of MyV1 and another one that just returns a MyV1. Now, it seems that the web client under hood always uses the first registered ResponseReader for any sort of response. If I call getMyV1 with the above order, I get a CCE. It works fine when I call getMyListV1, though. If I switch the order around, the service calls work vice versa as well.
