> Key: OWB-245
> URL: https://issues.apache.org/jira/browse/OWB-245
> Project: OpenWebBeans
> Issue Type: Bug
> Components: Injection and Lookup
> Affects Versions: M3
> Environment: Windows, Eclipse running Jetty.
> Reporter: Bill Wigger
> Assignee: Gurkan Erdogdu
> Fix For: 1.0.0
>
>
> As per section 3.3 of the spec:
> "If the producer method return type is a parameterized type, it must specify
> an actual type parameter or type variable for each type parameter."
> Problem using @Inject
> The below code fragment is for a parameterized type variable, and the inject
> is yielding an exception, instead of being injected properly.
> public class MethodTypeProduces1<T> {
> @Produces @Dependent @Named("ProMethodParameterized3") ArrayList<T>
> methodPT3() { ... }
> }
>
> Inject it as follows:
> public @Inject @Dependent @Named("ProMethodParameterized3")
> ArrayList<String> pt3;
> the following error occurs:
> javax.enterprise.inject.UnsatisfiedResolutionException: Api type
> [java.util.ArrayList] is not found with the qualifiers
> [...@javax.inject.named(value=ProMethodParameterized3)]
> at
> org.apache.webbeans.container.ResolutionUtil.checkResolvedBeans(ResolutionUtil.java:93)
> at
> org.apache.webbeans.container.InjectionResolver.getInjectionPointBean(InjectionResolver.java:232)
> Problem when access via the Bean Manager:
> Using this as the producer:
> @Produces @Dependent @Named("ProMethodParameterized3S") ArrayList<String>
> methodPT4() { .. }
> I can get a reference to it with the following code:
> TypeLiteral<ArrayList<String>> x = new TypeLiteral<ArrayList<String>>() { };
> Bean<ArrayList<String>> iBean = (Bean<ArrayList<String>>)
> manager.getBeans("ProMethodParameterized3S").iterator().next();
> ArrayList<String> as = (ArrayList<String>) manager.getReference(iBean,
> x.getType() , manager.createCreationalContext(iBean));
> But it this is the producer:
> public class MethodTypeProduces1<T> {
>
> //Test: Parameterized Field
> @Produces @Dependent @Named("ProMethodParameterized3") ArrayList<T>
> methodPT3() { ... }
> then the following fails:
> TypeLiteral<ArrayList<String>> x = new TypeLiteral<ArrayList<String>>() { };
> Bean<ArrayList<String>> iBean = (Bean<ArrayList<String>>)
> manager.getBeans("ProMethodParameterized3").iterator().next();
> ArrayList<String> as = (ArrayList<String>) manager.getReference(iBean,
> x.getType() , manager.createCreationalContext(iBean));
> with an exception when the manager.getReference(....) is called:
> java.lang.IllegalArgumentException: Given bean type :
> java.util.ArrayList<java.lang.String> is not applicable for the bean instance
> : Name:ProMethodParameterized3,WebBeans Type:PRODUCERMETHOD,API
> Types:...java.util.ArrayList...
