------------------------------
Summary: Unable to register a generic _InvocationCallback<Object>_
when using the async proxy client API in JAX-RS
Key: CXF-7147
URL: https://issues.apache.org/jira/browse/CXF-7147
Project: CXF
Issue Type: Bug
Components: JAX-RS
Reporter: John Poth
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.
