While true that the CLs didn't match, they wouldn't in this case, and I want to let the user know they're trying to inject into the wrong target type.

Clients of EJBs don't directly deal with the bean implementation class but instead a proxy which implements your business interfaces. Have a look at EJB 3.0 Core Specification Section 3.1.
