Sergey Beryozkin commented on CXF-5795:
---------------------------------------

This NPE was coming from a buggy code creating IllegalStateException about to be thrown due
to the entity stream not available. 
Cheers, Sergey

>             Project: CXF
>          Issue Type: Bug
>          Components: JAX-RS
>    Affects Versions: 2.7.11
>         Environment: Apache CXF 2.7.11
>            Reporter: Daniel Peder Dahlsveen

> The entity of a Response with HTTP status code 202 - Accepted is null. This causes a
NullPointerException when calling response.readEntity(). Furthermore, this bug seems to only
occur when using the JAXRSClientFactory, and it was introduced in CXF 2.7.11.
> The stacktrace is of the NullPointerException:
> java.lang.NullPointerException
> 	at org.apache.cxf.jaxrs.impl.ResponseImpl.doReadEntity(ResponseImpl.java:345)
> 	at org.apache.cxf.jaxrs.impl.ResponseImpl.readEntity(ResponseImpl.java:286)
> 	at org.apache.cxf.jaxrs.impl.ResponseImpl.readEntity(ResponseImpl.java:276)
> To recreate the bug do the following:
> Create a REST service that returns a 202 - Accepted with a non-null entity. In our case,
the service was for HTTP POST.
> Create a unit test that tests the service by creating a client with the JAXRSClientFactory
and then reads the entity from the response. 
> Both return Response.accepted(entity).build(); and return Response.status(Response.Status.ACCEPTED).entity(entity).build();
causes the bug.
