When integrating Seam into RHQ, I initially tried using Seam 2.1.1.GA, but it caused errors during deployment of rhq-portal.war that caused the deployment to fail. As I recall, the errors were related to JBoss clustering (unfortunately, I didn't save the errors). When I tried using Seam 2.1.0.SP1 instead, the errors did not occur. So something changed in either Seam 2.1.0.CR1, 2.1.0.CR2, or 2.1.0.GA that causes these errors to occur. This should be further investigated and a JBSEAM JIRA should be raised if necessary. There is currently no pressing reason to upgrade to Seam 2.1.1.GA, so this JIRA is low priority and definitely does not need to be addressed for the JON 2.2 release.
