org.jboss.as.testsuite.compat.jpa.hibernate.envers.HibernateEnvers3EmbeddedProviderTestCase#testServletSubDeploymentRead was added by AS7-928.
and it fails in some environment which i'm not sure.....
according to Scott Marlow's report, it fails on his environment every time and also Jesper's, but https://hudson.qa.jboss.com/hudson/job/JBoss-AS-7.0.x-stliu shows it pass w/o any issue.
we think it may caused by some (undeploy) cleanup is not occurring.
anyway, we have other test cases cover servlet usage, so we don't need it here.
