--------------------------------------------------------------------------

                 Key: JBAS-5671
                 URL: http://jira.jboss.com/jira/browse/JBAS-5671
             Project: JBoss Application Server
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Web (Tomcat) service
            Reporter: Adrian Brock

In jboss by default there is a root Tomcat context supplied by deploy/ROOT.war
This jsp page can be accessed using http://localhost:8080

If you attempt to deploy another war in the same context it correctly gives an error message

11:53:40,865 INFO  [TomcatDeployment] deploy, ctxPath=/, vfsUrl=

But it also removes the servlet bindings for the ROOT.war,

To reproduce:

1) Start jboss
2) Access http://localhost:8080 - gives a jsp page
3) In the testsuite, run ./build.sh one-test -Dtest=org.jboss.test.web.test.RootContextUnitTestCase
4) Refresh the page (make sure to flush the web browser cache)

If you look at Tomcat's JSR77 mbeans before and after, you'll see that the web module for localhost/ still exists,
but the servlet bindings have disappeared.
