Christian Kaltepoth commented on CXF-7501:
------------------------------------------
[~reta]: as mentioned in TOMEE-2122, injection works fine if the
{{ContainerRequestFilter}} is annotated with {{@Provider}}. But filters (and
other providers) can also be dynamically registered using the Feature contract
(https://docs.oracle.com/javaee/7/api/javax/ws/rs/core/Feature.html). In this
case injection doesn't work correctly. This is working fine with Jersey and
RESTEasy. See a more detailed description in TOMEE-2122

> Hey folks.
> We found a weird behavior while running MVC specification(JSR 371) on TomEE
> witch CXF. We have a *ContainerRequestFilter* defined called
> *JaxRsContextFilter*
> {code:java}
> @PreMatching
> @Priority(0)
> public class JaxRsContextFilter implements ContainerRequestFilter {
> @Inject
> private JaxRsContextProducer jaxRsContextProducer;
> @Context
> private Configuration configuration;
> @Context
> private HttpServletRequest request;
> @Context
> private HttpServletResponse response;
> public JaxRsContextFilter() {
> }
> public void filter(ContainerRequestContext requestContext) throws
> IOException {
> this.jaxRsContextProducer.populate(this.configuration, this.request,
> this.response);
> }
> }
> {code}
> You can see that we have a JaxRsContextProducer annotated to be injected as a
> field in our object but when JAXRSUtils is called to run the the container
> filters it injects the fields annotated as *@Context* , not the fields
> annotated with *@Inject*.
> {code:java}
> for (ProviderInfo<ContainerRequestFilter> filter : containerFilters) {
> try {
> InjectionUtils.injectContexts(filter.getProvider(),
> filter, m);
> filter.getProvider().filter(context);
> } catch (IOException ex) {
> throw ExceptionUtils.toInternalServerErrorException(ex,
> null);
> }
> {code}
> It causes our filter(*JaxRsContextFilter*) to throw a NullPointerException
> when filtering the request because it uses the producer to perform some
> actions in this operation.
> I believe this field should be injected as well, not only the *@Context*
> fields.
