CXFServlet fails to init with NPE at line 125 (updateContext) when run with embedded Jetty
and Spring3 - works with Spring 2.5.6
--------------------------------------------------------------------------------------------------------------------------------

                 Key: CXF-2620
                 URL: https://issues.apache.org/jira/browse/CXF-2620
             Project: CXF
          Issue Type: Bug
          Components: Transports
    Affects Versions: 2.2.5
         Environment: Spring 3.0.0.RELEASE / Jetty 6.1.8 (embedded)
            Reporter: William (BJ) Blackburn


I have been using CXF 2.2.3 (also tested with 2.2.5) with Spring 2.5.6 and an embedded Jetty
instance successfully for several months. After the release of Spring 3.0, I have tried migrating
to the new Spring version. Now the CXF Servlet is failing with a nullpointerexception on the
'updateContext' method:

Caused by: java.lang.NullPointerException
	at org.apache.cxf.transport.servlet.CXFServlet.updateContext(CXFServlet.java:125)
	at org.apache.cxf.transport.servlet.CXFServlet.onApplicationEvent(CXFServlet.java:182)
	at org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent(SimpleApplicationEventMulticaster.java:97)
	at org.springframework.context.support.AbstractApplicationContext.publishEvent(AbstractApplicationContext.java:294)
	at org.springframework.context.support.AbstractApplicationContext.publishEvent(AbstractApplicationContext.java:296)
	at org.springframework.context.support.AbstractApplicationContext.finishRefresh(AbstractApplicationContext.java:858)
	at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:419)

The line that is failing is:

   resourceManager.addResourceResolver(new ServletContextResourceResolver(servletConfig.getServletContext()));

I can only reproduce this issue using an 'embedded' jetty instance, I have attached a test
case. By switching between spring 2.5.6 and spring 3.0, you can see from the log output that
the servlet successfully initialized under 2.5.6, but fails under 3.0.

I understand this may be a very narrow case involving only this method of loading the servlet,
so if no fix is required in CXF, some advice as to a workaround would be very welcome. Thank
you.
