> It is currently impossible to register a generic _InvocationCallback<Object>_ when
invoking a method that returns void. This is due to a [check|https://github.com/apache/cxf/blob/master/rt/rs/client/src/main/java/org/apache/cxf/jaxrs/client/ClientProxyImpl.java#L797]
that isn't satisfied when the _methodReturnType_ is void. I propose to add the following case
> {code}
> Object.class == callbackRespClass
> {code}
> And let the user handle the logic.
>  I also propose to remove the condition
> {code}
> Response.class == callbackRespClass
> {code}
> Which will lead to failure when [casting|https://github.com/apache/cxf/blob/master/rt/rs/client/src/main/java/org/apache/cxf/jaxrs/client/JaxrsClientCallback.java#L76]
to a return type upon completion. I will provide a PR.
> [~sergey_beryozkin] sorry for the confusion.
