Subject [jira] [Commented] (CXF-5966) NPE in MessageContextImpl when setting ResponseBuilder entity in an ExceptionMapper
Date Tue, 26 Aug 2014 10:21:57 GMT

    [ https://issues.apache.org/jira/browse/CXF-5966?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14110577#comment-14110577
] 

Sergey Beryozkin commented on CXF-5966:
---------------------------------------

You are right, the JAXRS filter only registers itself as a native CXF interceptor, so the
problem persists. I recall now I did intrduce it to facilitate the registration from custom
DynamicFeatures. So I think the only workaround in the released 3.0.1 is to register a custom
out fault interceptor...the snapshots have it addressed though.

Re the annotations dependency, not a migration issue for sure given that it's a new and optional
dependency affecting the new 2.0 filters only but you are right it should've been mentioned
somewhere, I updated this section:
https://cwiki.apache.org/confluence/display/CXF20DOC/JAX-RS#JAX-RS-CXF3.0.0

thanks

> I hope that this description is complete enough. I think creating a test case for this
ticket will be more trouble than it's worth, but please let me know if you need me to.
> I have added BeanValidationInInterceptor to my JAX-RS service which uses JAXB-annotated
entities.
> I have created an ExceptionMapper to capture and write out the validation errors into
my JAXB-annotated object's 'description' field.
> In my exception mapper, I populate MyObject (which is JAXB-annotated), and then set it
as the entity:
> responseBuilder.entity(myObject);
> it results in an NPE as the JAXBElementProvider attempts to get any attachments from
the MessageContext, which dereferences a null OutboundMessage from its Exchange.
> Line 83 in MessageContextImpl contains:
> {code}
>     return m.getExchange().getOutMessage().get(Message.ATTACHMENTS);
> {code}
> The javadoc for Exchange.getOutMessage states that "During the inbound message processing,
the outbound message is null". 
> {code}
