[hibernate-dev] Hibernate.next version and AS 7.2 community release...

[Steve Ebersole]

Well I think one option would be to explore using Jandex within 
commons-annotations.  Jandex is meant as a very lightweight (read: 
FAST) annotation reader.  commons-annotations is meant to read 
annotations and merge the annotated values with xml overrides.  But 
commons-annotations could certainly use Jandex for the "read 
annotations" portion of its mandate (I think).  I think 
commons-annotations is slow also because of how it reads XML.  Reading 
XML is always going to be a balance between (relative) speed and 
readability/maintainability.  In the new ORM code, we moved to StAX + 
JAXB.  My preliminary testing showed that to be a pretty great 
compromise on that balance scale.  But commons-annotations does not at 
all work with JAXB nor JAXP.  As far as I know it just directly used 
dom4j apis (granted most likely because that is what ORM used).

And for the record, I never said throw commons annotations away.  
Stopping using it in a particular project moving forward is much 
different.  I just don't think it makes sense to write "throw away 
code".  I'd avoid fixing commons-annotations and retrofitting fixes 
into the old org.hibernate.mapping package.  We know that code is going 
away.  If someone wants to write such throw away code, be my guest :)
