CDI IllegalArgumentException

[R Yahiaoui]

 Hi, 

 I have the following code :

  Unmanaged unmanagedService = new Unmanaged<>(bm, _service_xx)               ;

  UnmanagedInstance serviceInstanceService = unmanagedService.newInstance() ;

  serviceInstanceService.produce().inject().postConstruct()                                       ;

  Object managedService = serviceInstanceService.get()                                           ;

 where "service_xx" is a class  annotated with @Counted and which is compiled at runtime.

 without "@Counted" averything works fine. 

 But with "@Counted" when I call "serviceInstanceService.produce().inject().postConstruct() ;" on the class " service_1" this works, 

 when I recall "serviceInstanceService.produce().inject().postConstruct() ;" on the "service_2", this throws the following exception :

(ServerService Thread Pool -- 13) null: java.lang.IllegalArgumentException: Can not set com.rac021.jax.api.streamers.IStreamer field com.rac021.jaxy.ghosts.services.vip_planes.Service.streamerOutputJson to org.jboss.weld.proxies.Service$Proxy$_$$_WeldSubclass

 Can someone tell me what's the problem

 Thanks

 Ideas about what's wrong ?

Which application server are you using?

With the limited info, I guess the previous unmanaged bean of server_xx is not a proxy. Once you have annotated with `@Counted' (which is an intercept binding), the instance you get will be a weld proxy. The injection will happen on the weld proxy (a subclass). Hope this might give you some pointer! If not, please share your code and post your question on relevant app server or weld-dev mailing list.

I'm using Thorntail ( wildfly swarm ) 

service_xx is a template file which is compiled at runtime ( after updating the patterns ) with the following code :

***************************************************************

@Counted(name = "{PACKAGE_NAME}" )

public class {SERVICE_NAME}

{

@Inject

 private IStreamer streamerOutputJson ;

@PostConstruct
public void init() { }

public {SERVICE_NAME} () { }

@GET
@Produces("json/plain")
public Response getResourceASJson( @HeaderParam("Keep") String filterdIndex )

{ ... }

}

***************************************************************

It seem that streamerOutputJson can't be injected ( When the annotation @Counted is used )

For the record, an issue has been created for the problem and the problem is being addressed there: https://issues.jboss.org/browse/THORN-2100

Thank you Michal for the update! Glad to know Thorntail is investigating this!

Thanks
