Any reason we couldn't make org.jboss.seam.security.permission.Permission an interface (and make JPAPermissionStore, the only internal class instantiating Permission, turn the existing class into JPAPermission implements Permission)?
This is so that PermissionStore implementations can return instances of existing classes with existing superclasses. Like the one I have to implement today :)
If that's reasonable, I'll open a JIRA on it with a patch.
