------------------------------------
Summary: MethodDispatcher may return invalid method for
OperationResourceInfo object
Key: CXF-7647
URL: https://issues.apache.org/jira/browse/CXF-7647
Project: CXF
Issue Type: Bug
Components: JAX-WS Runtime
Affects Versions: 3.2.2
Reporter: Martin Basovnik
Imagine the following JAX-RS resource classes:
{code:java}
public interface VersionedResource<CDTO, UDTO, ID extends RequestParam<UUID>>
extends Resource<CDTO, ID> {
Response update(ID idParam, IfMatchHeader ifMatchHeader, UDTO updateDto);
@Deprecated
default Response updateByPost(ID idParam, IfMatchHeader ifMatchHeader, UDTO
updateDto) {
return update(idParam, ifMatchHeader, updateDto);
}
}
{code}
{code:java}
@Path(BASE_PATH + USERS_PATH)
public interface UserResource extends VersionedResource<UserCreateDto,
UserUpdateDto, UserIdParam> {
...
@PATCH
@Path(UserId.PATH)
@Override
Response update(
@BeanParam UserIdParam userIdParam,
@BeanParam IfMatchHeader ifMatchHeader,
@Valid UserUpdateDto userUpdateDto
);
@POST
@Path(UserId.PATH)
@Override
default Response updateByPost(
@BeanParam UserIdParam userIdParam,
@BeanParam IfMatchHeader ifMatchHeader,
@Valid UserUpdateDto userUpdateDto) {
return VersionedResource.super.updateByPost(userIdParam, ifMatchHeader,
userUpdateDto);
}
...
}
{code}
[MethodDispatcher|https://github.com/apache/cxf/blob/master/rt/frontend/jaxrs/src/main/java/org/apache/cxf/jaxrs/model/MethodDispatcher.java#L29]
contains its internal collections in *non-deterministic* order.
There are two mappings for method {{updateByPost}} and two possible returned
methods:
*a)*
{code:java}
public default Response UserResource.updateByPost(RequestParam, IfMatchHeader,
java.lang.Object)
{code}
{{RequestParam}} is abstract class which results in {{InstantiationException}}
[later|https://github.com/apache/cxf/blob/cxf-3.1.11/rt/frontend/jaxrs/src/main/java/org/apache/cxf/jaxrs/utils/JAXRSUtils.java#L1054].
*b)*
{code:java}
public default Response UserResource.updateByPost(UserIdParam, IfMatchHeader,
java.lang.Object)
{code}
In this case everything works.
Is it possible to somehow detect overridden methods and filter them from
evaluation?
