Right, it doesn't make sense to use the TCCL to locate the 
system-wide/singleton ORB and then cache it but clearly some 
applications that were bundle their own ORB with conflicting 
configuration are running into this. The change in the webrev looks okay 
to me (for 8u, not 9 where I agree that we keep the correct behavior).
