Re: [jboss-dev] jbossas -beans.xml opt
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.
