---------------------------------------
Summary: NullPointer exception in
cxf.endpoint.ClientImpl.onMessage(ClientImpl.java:719) (was: NullPointer
exception in )
> NullPointer exception in

>
> Key: CXF-6354
> URL: https://issues.apache.org/jira/browse/CXF-6354
> Project: CXF
> Issue Type: Bug
> Affects Versions: 2.7.2
> Reporter: Sanjeet Karamchandani
> Priority: Critical
>
> I have a requirement where I need to move a webservice call to a seperate
> thread so that I could retry if it doesn't complete within a time limit. To
> achieve I moved my webservice call to a futuretask and in my main thread I am
> doing a task.get(timeout). A webservice call that is normally completed in
> few miliseconds doesn't complete even after 10 mins if I move it into a
> seperate thread call.
> Is there a problem with CXF. I am getting a NullPointer exception around the
> cxf.endpoint.ClientImpl.onMessage() call. Stacktrace at the end.
> I am including the code thats causing problems only when I move the call in a
> seperate thread.
