I'm using JBoss 7.1.1.Final and am building a WAR application using Spring 3.1.1.RELEASE and Hibernate 4.1.5.Final. The Hibernate version is a slight upgrade from what module JBoss provides. My question is, are there performance (or other) disadvantages of doing this? I would prefer not to install a new module in JBoss because there may be other applications running that depend on the Hibernate version taht ships with JBoss.
