The update looks good.  Thanks.

What I request to add is a test setting the system property 
(-Dsun.cds.enableSharedLookupCache=true) and continue to load class A 
and B.  Removing line 44-58 should do it and also no need to set 
-Dfoo.foo.bar.

It'd be good if you run this test and turn on the debug traces to make 
sure that the application class loader and ext class loader will start 
up with the lookup cache enabled and make up call to the VM.  As it 
doesn't have the app cds archive, it will invalidate the cache right 
away and continue the class lookup with null cache array.
