[jira] [Updated] (CXF-6793) InvocationCallback doesn't try to get response class type

["Romain Manni-Bucau (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CXF-6793?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Romain Manni-Bucau updated CXF-6793:
------------------------------------
    Description: 
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
