[jira] [Commented] (CXF-6354) NullPointer exception in
cxf.endpoint.ClientImpl.onMessage(ClientImpl.java:719)
[ https://issues.apache.org/jira/browse/CXF-6354?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15943826#comment-15943826 ]
Daniel Kulp commented on CXF-6354:
----------------------------------
We need a test case for this.
In general, the beans shouldn't be used until the spring context is completely up and running. Not sure what you are doing that is causing that to not be the case.
> NullPointer exception in cxf.endpoint.ClientImpl.onMessage(ClientImpl.java:719)
> -------------------------------------------------------------------------------
>
> Key: CXF-6354
> URL: https://issues.apache.org/jira/browse/CXF-6354
> Project: CXF
> Issue Type: Bug
> Components: JAX-WS Runtime
> Affects Versions: 2.7.2
> Reporter: Sanjeet Karamchandani
> Priority: Critical
> Fix For: NeedMoreInfo
>
>
> Updated: Please see the comments. This is caused due to a deadlock.
> Overall since DefaultSingletonBeanRegistry is being called from main thread and CXF tries to use it in a seperate thread, it causes deadlock.
> See the comments:
> https://jira.spring.io/browse/SPR-8471
> --------------------
> 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.
> Is there a problem with CXF. I am getting a NullPointer exception around the cxf.endpoint.ClientImpl.onMessage() call. Stacktrace at the end.
> Please help as I am stuck with no clues.
> I am including the code thats causing problems only when I move the call in a seperate thread.
