Steve Ebersole commented on HHH-2153:
-------------------------------------
bytecode provider is one of a few properties in Hibernate that are currently "global". By global we mean scoped within a classloader (specifically the classloader for the Hibernate Environment class).
This is very complex to change (it has been discussed quite a few times on the dev list, so I will not expound on it here), although it is planned to change such that this is eventually a SessionFactory-scoped property.
JBossAS wants to use javassist simple to avoid bundling another dependency.

> It is not possible to set the bytecode provider by hibernate.properties, because jboss ejb3.deployer sets it in System.properties. System.properties is added to the GLOBAL_PROPERTIES in Environment.class after hibernate.properties and overwrites the values in hibernate.properties. A solution would be to change the order of adding the properties to GLOBAL_PROPERTIES. First add System.properties, then add hibernate.properties, to be able to overwrite as needed
