[jboss-dev] How can a project run in both AS 4.2.0 and AS 5.0?

[Jason T. Greene]

+100 All integration code should live in AS. Otherwise it becomes nearly 
impossible to make large changes to AS, since such integration modules 
rely on internal implementation details. Not to mention it would be a 
royal pain to track down and fix each component, since they would be in 
separate repositories.
