title: JBAS011006 Not installing optional component StandardServletAsyncWebRequest due to exception DeploymentUnitProcessingException
body: <p>Since, Spring 3.2 GA release is out I wanted to upgrade my Spring 3.1.2 application to the newest release. The application runs on JBoss 7.1.1.Final. Everything else went fine except that I get the below JBoss error message which I find annoying (though the app runs ok). Any idea?</p>
