[hibernate-dev] Integrator locator

[Steve Ebersole]

So a slight concern.  The javadocs for java.util.ServiceLoader state 
that its load(Class) method uses TCCL.  Given the recent issues we have 
had with TCCL and JBoss AS 7 I wonder if its better to use the explicit 
load(Class,ClassLoader) version?

There the question becomes what ClassLoader to use.  We do have the 
ClassLoaderService which is meant to abstract away access to the 
underlying ClassLoader(s), however its API does not allow access to 
those ClassLoader(s) themselves.
