JBoss ON 3.2 upgrade fails with"JBAS014802: Cannot resolve expression 'expression "${rhq.server.log-level}"'"

Issue

• We ran the upgrade but the server upgrade seems to hang with the rhq-installer.log stating:

10:49:14,864 ERROR [org.rhq.enterprise.server.installer.Installer] The installer will now exit due to previous errors: org.rhq.common.jbossas.client.controller.FailureException: Failed request: JBAS014802: Cannot resolve expression 'expression "${rhq.server.log-level}"' -- java.lang.IllegalStateException: Failed to resolve expression: ${rhq.server.log-level}
