Subject Re: OpenJPAPersistence extends Persistence; should we remove this?
Date Wed, 08 Aug 2007 16:29:39 GMT

I don't know anything about the nature of the problems with the  
Persistence provider registry, but I don't see any reason why  
OpenJPAPersistence should need to extend Persistence.

However, I can't imagine how simply removing the inheritance  
connection would solve anything. Are you suggesting that we replicate  
the Persistence functionality (like createEntityManagerFactory()) in  
our own OpenJPAPersistence class?
