Subject [jira] [Commented] (CXF-6793) InvocationCallback doesn't try to get response class type
Date Mon, 22 Feb 2016 14:54:18 GMT

    [ https://issues.apache.org/jira/browse/CXF-6793?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15157084#comment-15157084
] 

Romain Manni-Bucau commented on CXF-6793:
-----------------------------------------

Just reading the test I think the callbacks are not type variables. Try adding <T> and
InvocationCallback<T> even if it is useless language wise.

> in org.apache.cxf.jaxrs.client.WebClient#doInvokeAsyncCallback the webclient could try
to find the response class if not there.
> would avoid to give a null type the providers can't use to do what they need to
> Code can be if respClass is null and callback is not null something like:
> {code}
> // in real code filter interfaces and dont access them directly by index
> ParameterizedType.class.cast(callback.getClass().getGenericInterfaces()[0]).getActualTypeArguments()[0]
> {code}
> edit: digging a bit seems org.apache.cxf.jaxrs.utils.InjectionUtils#getSuperType just
doesn't default to anything and in case of TypeVariable unbounded is not able to default to
Object so if bound is really Object it fails
> if it helps here is the code I use: https://gist.github.com/rmannibucau/09a084c28d8b61c232cf
- of course would like to make the class geenric (<T>) and remove this String typing
;)
