Yes, I don't like the -all.jar s particularly, however I don't see a nice way around it (Seam's deps are different than those in the -all.jar) However, this will all go away when we can target JBoss AS 5 with Seam (as this is what Embedded is based on, and so we can sync jar versions easily). This should be soon. I don't know how to order the classpath with Maven (it's easy with ant) but you need to make sure the -all jars come before everything else when running tests.
