EAR Seam project running with Seam 2.1.2.CR ok.
Changed Seam runtime in Seam Settings of Properties for the project from jboss-seam-2.1.2.CR2 to jboss-seam-2.1.2.GA.
After starting JBoss AS, [ServletContextListener] Welcome to Seam 2.1.2.CR2 is still written to the log instead of the new seam version.
By the way, this was also the case when upgraded from Seam 2.1.1.GA to Seam 2.1.2.CR2. I ended up creating a new Seam Project with the 2.1.2.GA setting and then manually copied the files into the new project from the old Seam 2.1.1.GA project in Eclipse in order to force the upgrade. Looks like this still necessary for 2.1.2.CR2 to 2.1.2.GA due to this bug.
