And now you speak, after 3years of work. :-)

True, see DeployerWrapper.
But that's much better, since you at least know what you can expect from TCCL.

All CL in JBossAS has been re-written to use the new CL layer.
See bootstrap.xml and its 'children'. So I doubt even bootstrap cl is NACL.
And deployers are nothing else than pojos in MC, hence they also use the new cl layer.

If you don't provide any additional info,
things will behave as the old cl layer - import/export all.
But new cl layer can mock OSGi kind of classloading,
hence you can do fine grained scoping, OSGi style. ;-)

There are many different ways to do this.
