      Workaround 1

      Annotate the ContextResolver with @Dependent to prevent Weld from using a proxy.

      Workaround 2

      Don't use @Provider or CDI scope annotations such as @ApplicationScoped or @RequestScoped on the ContextResolver that is registered via @RegisterProvider. To make the provider work with REST resources you can then create an empty subclass of the context resolver and annotate that subclass with @Provider.

To make the provider work with REST resources you can then create an empty subclass of the context resolver and annotate that subclass with @Provider .

      When registering a custom context resolver class via @org.eclipse.microprofile.rest.client.annotation.RegisterProvider you get an ArrayIndexOutOfBoundsException if the context resolver class ist annotated with @Provider.
      In my example I have an ObjectMapperProvider to register a custom Jackson ObjectMapper and i want to annotate it with @Provider so that it gets picked up by my REST resources. To also make it available to my rest clients i use @RegisterProvider:

      @Provider
@Produces(MediaType.APPLICATION_JSON)
public class JsonObjectMapperProvider implements ContextResolver<ObjectMapper> {
  // ...
}

@RegisterProvider(MyContextResolver.class)
public interface MyRestClient {
 // ...
}

      The issue is that when using @Provider the provider is an instance of WeldProxy for some reason (probably @Provider implies a non-dependent scope) and this causes org.jboss.resteasy.spi.util.Types.findInterfaceParameterizedTypes(Class<?>, ParameterizedType, Class<?>) to get a non-parameterized class object when calling root.getGenericInterfaces() in line 535 in version 6.2.4.Final. In the Javadoc of java.lang.Class.getGenericInterfaces() I read:

      Returns the Types representing the interfaces directly implemented by the class or interface represented bythis Class object.

      So my guess is that maybe the Weld proxy reimplements the ContextResolver interface without generic type parameters. So i would propose to make Types.findInterfaceParameterizedTypes check the superclass in case the generic type parameter cannot be determined from the subclass, similar to how the superclass is already used when the interface is not present on the subclass.
