Problem (un)Deploying Web Module on Root Context [/]

Question

Hello all,
I have been attempting to deploy an EAR that has multiple web and ejb modules. All of the ejb modules deploy correctly and all but one of the web modules deploy correctly. The one that I am having problems with is the web module at the root context []. If the application server is already running when I try to deploy, I get the following error: (unimportant part removed)
INFO|javax.enterprise.system.container.web|WEB0113: Virtual server [server] already has a web module loaded at [/]; therefore web module [BlueCommerce:web-client.war] cannot be loaded at this context path on this virtual server.However, I have no module loaded at the root. I have also tried this on a newly created domain. Is there some default web module that I must remove first.
After the deploy fails, if I restart the application server I can access it, but all the security-constraints seem to be gone. Also, I cannot undeploy it without restarting the application server. When I attempt to do so, I get the following error:
SEVERE|javax.enterprise.system.container.web|[WebContainer] Undeployment fail for context /Any assistance would be appreciated. Thank you,

The behaviour you are seeing is expected.
Notice that the container automatically defines and loads a default web
module with context root "/" if no such module has been defined among
the web modules and j2ee applications to be deployed on a virtual
server, and if the virtual server does not specify a
"default-web-module" attribute.
This default web module's docbase it set to the virtual server's docroot.
Therefore, in the case of the virtual server named "server", a default
web module with docbase SUNWappserver/domains/domain1/docroot is loaded
at the context root "/", which is why you see the index.html stored in
the above docbase when you access http://<host>:<non_admin_port>.
Once a web module has been deployed to a particular context root on a
virtual server, it cannot be overridden.
