Re: Inner Class Entities

[Craig L Russell <Cr...@Sun.COM>]

Hi Tim,

Just following up.

I never understood why *static* inner classes could not be Entities.  
I'm just guessing that some vendors didn't like them for some reason.

But non-static inner classes would be more like dependent classes  
whose existence depended upon the existence of the "owning" outer  
class. And there are some issues with metadata here.
