--------------------------------
Resolution: Fixed
> Sending an empty soap body message to a generic provider camel-cxf consumer
> results in NPE

> Key: CAMEL-7069
> URL: https://issues.apache.org/jira/browse/CAMEL-7069
> Project: Camel
> Issue Type: Bug
> Components: camel-cxf
> Affects Versions: 2.12.2
> Reporter: Aki Yoshida
> Assignee: Aki Yoshida
>
> In some cases, CXFPayload is instantiated with a null body and this is
> causing an NPE later in the processing.
> Caused by: java.lang.NullPointerException

> What is not sure is how we should fix it.
> CXFPayload is not checking whether the body is null when it is instantiated.
> In that case, some methods will lead to NPE but some are not (like
> getBodySources() or getHeaders()). And there are some test cases passing a
> null body.
> So I think, we should either
> 1. change CXFPayload to automatically creates an empty body (i.e., an empty
> List<Source>) when the body passed to the constructor is null, or
> 2. add this null->empty handling in DefaultCXFBinding.getPayloadBodyElements
> when extracting the body and pass an empty list to the CXFPayload constructor
> in this case, or
> 3. just throws a specific exception instead of NPE in this particular case.
> In any case, we need to clarify what is the correct usage of CXFPayload.
