The tests:
org.jboss.test.hello.test.HelloHttpStressTestCase
org.jboss.test.hello.test.HelloClusteredHttpStressTestCase
org.jboss.test.naming.test.SimpleUnitTestCase.testHttpInvoker()
(plus likely a few others) are failing due to the HTTP invoker service configuration files no present in:
deploy/httpha-invoker.sar/META-INF
deploy/httpha-invoker.sar/invoker.war/WEB-INF

I have not confirmed if this was intentional.

JBAS-7130 is related to the same issue but is being addressed as a bug in JSF not handling the absence of the web.xml.

With this issue being exposed, it might be a good opportunity to revisit JBAS-5464 as there was no reply on the related forum discussion.
