IMO, no. EE is simply *restricting* where 299 and 330 may be used.  
Given that EE consumes the 299 and 330 specs, I think this is  
perfectly valid (whether it is desirable is another matter ;-). I  
don't see why 299 or 330 need to also restrict themselves in this way.

The 299 states this explicitly (not implicitly).

3.12 defines which beans are new beans

This clearly states that any class in the application class path is  
represented by a new bean. As an optimisation, the implementation may  
choose to only create new beans for injection points it detects with  
@New specified.

So, we have established that these classes are new (managed) beans.

Now, if you look at 5.6.4, you'll see that the 299 spec requires that  
Java EE component environment resources are injected into all managed  
beans.

This is a snapshot of the repo without these changes:
