We are working on our new system which is built using Jboss, Spring and Hibernate and at the moment we\'re in the progress of migrating from AS 7.1 to EAP 6.0.
Ensure that you are not using Spring Framework versions between 2.5 and 3.0.1. These are known to be incompatible with all versions of JBoss from 5.0 or so and newer;
