----------------------------
Summary: Json API client does not work with Jackson 2.2
Key: CXF-5220
URL: https://issues.apache.org/jira/browse/CXF-5220
Project: CXF
Issue Type: Bug
Components: JAX-RS
Affects Versions: 2.5.11
Reporter: bc Wong
JacksonJsonProvider in Jackson 2.2 changes the signature to:
{noformat}
JacksonJsonProvider extends ProviderBase<JacksonJsonProvider, ObjectMapper,
JsonEndpointConfig, JsonMapperConfigurator>
{noformat}
That means it'll never get picked as a candidate for a message reader, because
{{ProviderFactory#handleMapper}} has this:
{noformat}
Class<?> mapperClass = ClassHelper.getRealClass(em.getProvider());
Type[] types = getGenericInterfaces(mapperClass);
for (Type t : types) {
if (t instanceof ParameterizedType) {
ParameterizedType pt = (ParameterizedType)t;
Type[] args = pt.getActualTypeArguments();
for (int i = 0; i < args.length; i++) {
Type arg = args[i];
if (arg instanceof TypeVariable) { // <------ Always fail
TypeVariable var = (TypeVariable)arg;
Type[] bounds = var.getBounds();
{noformat}
And the symptom is that my API client (which has a dependency on Jackson 2.2.2)
errors out like this:
{noformat}
Caused by: javax.ws.rs.WebApplicationException:
javax.xml.bind.UnmarshalException: unexpected element (uri:"", local:"items").
Expected elements are
<{}cluster>,<{}clusterList>,<{}clusterRef>,<{}config>,<{}configList>,<{}healthCheck>,<{}parcel>,<{}role>,<{}roleConfigGroup>,<{}roleConfigGroupRef>,<{}roleTypeConfig>,<{}service>,<{}serviceConfig>,<{}serviceRef>
