They have since ripped out any kind of OSGi support. They wrote their own module system [1]. It's basically their very fancy way set up their own class loaders.

They have since ripped out any kind of OSGi support. They wrote their own module system [1]. It's basically their very fancy way set up their own class loaders. As far as class loader frameworks go it's one of the best out there, IMHO the best of any Java server or container. It gives you non-hierarchical class loading and is fully parallel capable. Applications in general don't have to deal with it unless they want to tweak class loading. Only extensions to JBoss/WildFly itself have to deal with it, mostly it's just XML descriptors.
