Re: [hibernate-dev] classloading issue when trying to add envers to as7

1. adding envers into org.hibernate module in as7, so user's app can see both hibernate and envers class (with an separate envers module i ran into some cycle dependency issue)

2. envers throws "listeners were not registed" exception, means hibernate's IntegratorServiceImpl can't see envers class/resource IntegratorServiceImpl is using java.util.ServiceLoader#load(Class<S> service), which internally using TCCL, (I think) that's the reason why core can't see envers' integrator. so, i created a custom ServiceLoader which use ClassLoaderService to find the integrator, but this doesn't work either. since, we need org.hibernate.service.classloading.internal.ClassLoaderServiceImpl#locateResources first (META-INF/services/org.hibernate.integrator.spi.Integrator) and ClassLoaderServiceImpl using resourceClassLoader to do this. by default, resourceClassLoader is set to applicationClassLoader in ClassLoaderServiceImpl. then, i changed IntegratorServiceImpl to use java.util.ServiceLoader#load(Class<S> service, IntegratorServiceImpl.class.getClassLoader() ), test pass, but this of course is not the fix. so, i changed the custom ServiceLoader to use classLoaderService to locateResources first, and using ServiceLoader.class.getClassLoader() to reload the resource again. here are the changes: https://github.com/stliu/hibernate-core/commit/09ce5defabea8cfb87d06c3d7b... https://github.com/stliu/jboss-as/commit/616237755626672157fb2ae565fadb16... thoughts?
