AS7 gives NPE when jboss-web.xml is missing from WAR

I'm trying to deploy a simple WAR (nearly empty, with a single JAX-WS web service) using a fairly recent snapshot of JBoss AS7. If I do not include jboss-web.xml in the WEB-INF folder, I get the following NPE when deploying to standalone\deployment

12:17:25,356 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-3) MSC00001: Failed to start service jboss.deployment.unit."jaxws-test.war".INSTALL: org.jboss.msc.service.StartException in service jboss.deployment.unit."jaxws-test.war".INSTALL: Failed to process phase INSTALL of deployment "jaxws-test.war"

When I add a very simple jboss-web.xml file (containing only the context-root tag), the deployment succeeds.

Attached is the WAR file.
