When a library is loaded this way, the classes show up in the
bootstrap loader.  (FWIW, in 3.4.x, there is some deep confusion about
the bootstrap and system loaders in libgcj.)

The first problem with this approach is just that it prevents you from
loading two different versions of the library under different class
loaders.  The second one is that some applications aren't prepared to
have classes they "know" will be loaded by one of their custom class
loaders to magically appear in the system loader.
