CXF & NIO & JAX-RS 2
Hi,
This February there was a thread titled "Server Side Asynchronous processing support via CXF & NIO support" regarding an NPE thrown at AsyncResponseImpl.java:240 when trying to use AsyncResponse. I get a simmilar stacktrace, and I prepared an own simple test maven project demonstrating the issue (attached to the email).
In short:
1. I use latest Jetty: 8.1.15.v20140411.
2. In web.xml i have both 'version="3.0"' and '<async-supported>true</async-supported>'.
3. My rest resource api is declared using AsyncResponse.
And still i get this:
java.lang.NullPointerException
at org.apache.cxf.jaxrs.impl.AsyncResponseImpl.initContinuation(AsyncResponseImpl.java:240)
at org.apache.cxf.jaxrs.impl.AsyncResponseImpl.<init>(AsyncResponseImpl.java:58)
at org.apache.cxf.jaxrs.utils.JAXRSUtils.processParameter(JAXRSUtils.java:775)
at org.apache.cxf.jaxrs.utils.JAXRSUtils.processParameters(JAXRSUtils.java:749)
at org.apache.cxf.jaxrs.interceptor.JAXRSInInterceptor.processRequest(JAXRSInInterceptor.java:236)
at org.apache.cxf.jaxrs.interceptor.JAXRSInInterceptor.handleMessage(JAXRSInInterceptor.java:101)
at org.apache.cxf.phase.PhaseInterceptorChain.doIntercept(PhaseInterceptorChain.java:271)
.......
Am I missing something? Can it be some async setup that is missing in my jaxrs:server declaration inside applicationContext.xml? Currently i have there:
<jaxrs:server address="/api">
<jaxrs:properties/>
<jaxrs:serviceBeans>
<ref bean="apiResourceBean"/>
</jaxrs:serviceBeans>
<jaxrs:providers>
<ref bean="jacksonProvider"/>
</jaxrs:providers>
<jaxrs:features>
<cxf:logging/>
</jaxrs:features>
</jaxrs:server>

Best regards
Michael

Yes, you are right, thanks, it helped. In my web.xml there was MDCInsertingServletFilter filter declared without "<async-supported>true</async-supported>" and that was the cause.
