---------------------------------------
Can you please post a sample resource class (with the root Path annotation),
and a sample request URI. I can't reproduce this NPE at the moment.
> JAXRSOutInterceptor throws NullPointerException for unknown requests when
> using exception mapper

> Key: CXF-1858
> URL: https://issues.apache.org/jira/browse/CXF-1858
> Project: CXF
> Issue Type: Bug
> Components: REST
> Affects Versions: 2.1.2
> Environment: windows XP, jdk1.6.0_07, tomcat 6.0.18
> Reporter: david
>
> JAX-RS webservice
> When a client requests URL that isnt a valid service endpoint and using an
> Exeption mapper to return more detailed error, if you add an entity in the
> response the JAXRSOutInterceptor throws a NPE.
> java.lang.NullPointerException
> at
> org.apache.cxf.jaxrs.interceptor.JAXRSOutInterceptor.processResponse(JAXRSOutInterceptor.java:150)
> at
> org.apache.cxf.jaxrs.interceptor.JAXRSOutInterceptor.handleMessage(JAXRSOutInterceptor.java:61)
> .....
> The exception mapper:
> public class MyExceptionMapper implements ExceptionMapper<Exception>
> {
>
> private static Logger LOG =
> LogUtils.getL7dLogger(MyExceptionMapper.class);
>
> @Override
> public Response toResponse(Exception ex)
> {
> LOG.logp(Level.WARNING, "MyExceptionMapper",
> "toResponse","Caught Exception:", ex);
> return
> Response.status(503).type("text/html").entity("Myexception error
> description").build();
> }
> }
> If I dont put the entity in the response it works, but with an entity in the
> response it causes a NullPointerException.
> currently in SVN and 2.1.2 JAXRSOutInterceptor.java line 150 is :
> writer.writeTo(responseObj, targetType, invoked.getGenericReturnType(),
> invoked != null ? invoked.getAnnotations() :
> new Annotation[]{},
> responseType,
> response.getMetadata(),
> out);
>
> perhaps should be this :
> writer.writeTo(responseObj, targetType,
> invoked != null ?
> invoked.getGenericReturnType() : null,
> invoked != null ? invoked.getAnnotations() :
> new Annotation[]{},
> responseType,
> response.getMetadata(),
> out);
