Dan Allen commented on JBSEAM-3996:
-----------------------------------

I want to emphasize that solving this issue is not as straightforward as it might appear. Seam was designed so that one component could override another with the same component name and class using precedence rules. Now we are saying that if there is a conflict, it should still not fail. Let's just think this through rather than put in a quick fix.

> As discussed in JBIDE-3623 then Seam is reporting "Two components with the same name and precedence - component name: <name>, component classes: <classname>" when the class name is exactly the same. In that case it should only be the one that is first on the classpath that is used; that the class exist in other locations is irrelevant since you won't be able to load the class anyway since in java classloading first-found wins.
