I don't know the answer here.  I don't think the code cache has to do 
with the
number of loaded classes so much as  the amount of compiled code.
I remember before code cache flushing the code cache would fill up and then
compilations would shut down.  I don't recall a full code cache causing
a GC but that's JIT stuff so I don't know for sure.
