back port fix from JBSEAM-4316-Classloader cannot find XML files in multiple WARs

                 Key: JBSEAM-4620
                 URL: https://jira.jboss.org/jira/browse/JBSEAM-4620
             Project: Seam
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.2.0.CR1
         Environment: JBoss AS 5.0.0.GA. Seam 2.2 r11299
            Reporter: Reind D
            Assignee: Marek Novotny
             Fix For: 2.2.1.CR1

I have an EAR that contains multiple WAR files. The first webapp to be accessed works fine. Any web request to the 2nd WAR to be accessed causes the following error:

WARN [VFSScanner] Error handling item 'login/index.page.xml': java.lang.NullPointerException: Cannot find URL from classLoader for login/index.page.xml, loading from org.jboss.web.tomcat.service.WebCtxLoader$ENCLoader at 1ed964f 

FileDescriptor.java calls:

   Resources.getResource(name, ServletLifecycle.getServletContext());

Which returns a static reference to the ServletContext which is overwritten by the last webapp to be initialized.

   private static ServletContext servletContext;

   public static ServletContext getServletContext()
      //don't throw an exception if null, because of unit tests
      return servletContext;

The 2nd webapp to be initialized will have a reference to the first webapp's ServletContext.
