This is existing logic that I did not replace/alter that I know of.  I believe 
that it works as needed based on the fact that it causes a new ClassLoader to be 
created if one of the pieces of the codebase is not reachable.  Thus you will 
get class incompatibility which is at least a partially better result than using 
an incomplete codebase.
