Summary: 0003111: RequestWrapper throws NPE
Description: A call to getSession() results in a NPE thrown from com.caucho.server.connection.RequestWrapper.isSecure

This issue has already been reported as 0002883 but was closed based on an assumption that the NPE was caused by application error. I am able to reproduce by simply submitting a request that should return a 404. As the Request is torn down, RequestWrapper is invoked and triggers the NPE.

Identical requests running on Jetty and running on Tomcat are handled without any error. At a minimum, I need this patched to throw a meaningful non-runtime Exception. Ideally, Resin would exhibit the same expected behavior as Tomcat and Jetty. My trace is pasted below:

BTW: the referenced ticket 0002883 is not mine, so this issue is affecting at the very least two different Resin users.

I have exactly the same error message with resin-3.1.6 and spring-framework-2.5.5.

I just want to get HttpServletRequest from my bean :

The following single line triggers the exception :

ServletRequestAttributes sra = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
System.out.println("ServletRequestAttributes = " + sra);

ServletRequestAttributes is correctly retrieved , and printed :
ServletRequestAttributes = HttpRequest[34]

But the exception is thrown and logged...

Sorry for my previous post .
Now , I can pinpoint the problem.

The problem comes from Spring's RequestContextListener.

<listener>
    <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
</listener>

Once it is registered in web.xml , each web request will triggger the NPE :


The following exception results from Resin 3.2.1 with Spring 2.5.5 :

I've upgraded to Resin 3.1.9 (pro) and this issue remains.
