[jboss-dev] jbossas -beans.xml opt

[David M. Lloyd]

That sounds like a good idea.  Consider also the growing number of bean 
declarations that are currently created programmatically by other deployers 
- most (maybe all) of these would have to be refitted to add these 
annotations.  Better to keep the defaults to the common case if possible.
