Agreed on all parts.  If the default CL isn't set then TCCL is probably 
a reasonable default.  But the user should be allowed to set the default 
class loader for resolution.  To be fair though I don't know whether 
that makes sense at a cache level, but from a marshalling and modularity 
perspective this makes a lot of sense.
