Description

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.
