Multiple war files with same context path but different virtual host cause "Web mapping already exjsts for deployment"

Example: Two war's will be deployed, The first has virtual-host=www.foo.com and context-root="/", the second has virtual-host=www.bar.com and context-root="/".

This will cause an exception with message "Web mapping already exjsts for deployment" from org.jboss.web.tomcat.service.deployers.TomcatDeployer.performDeployInternal line 214.

The cause of the issue is in TomcatDeployer.mapVirtualHosts, see the forum post for an analyze. A sidenote, the javadoc is incorrect on that method as well.
