Description of problem:

access-log setting does not log 404 for non-existent context when enable-welcome-root is set to false in EAP 6


Steps to Reproduce:

1. Configure web subsysmte to set enable-welcome-root to "false" and enable access-log. For example:

        <subsystem xmlns="urn:jboss:domain:web:1.4" default-virtual-server="default-host" native="false">
            <connector name="http" protocol="HTTP/1.1" scheme="http" socket-binding="http"/>
            <virtual-server name="default-host" enable-welcome-root="false">
                <alias name="localhost"/>
                <alias name="example.com"/>
                <access-log/>
            </virtual-server>
        </subsystem>

2. Access non-existent context and get 404 like:

    curl -v http://localhost:8080/foobar

3. Check the access log


Actual results:

Nothing is logged in the access logging.


Expected results:

404 should be logged in the access logging.
