Max Rydahl Andersen reopened JBSEAM-3996:
-----------------------------------------



Looking at the patch I do not believe this will solve it.

The comparison should be based on the classname to avoid any problems with classpath order and different classloaders.

Since Seam should only have access to *one* class within one classloader it should be enough to compare the class name.

> 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.
