> 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.
