[Bug classpath/23921] gnu.classpath access restrictions are not enforced by default

We ran into a problem related to this with JikesRVM.  JikesRVM does have
protection on the java and gnu.classpath namespaces, which means that in
previous releases (it's fixed in svn, but via a hack) it would block running
any of the classpath tools or examples.  We now block only:

       "Lgnu/classpath/debug/".getBytes(),
       "Lgnu/classpath/jdwp/".getBytes(),
       "Lgnu/classpath/NotImplementedException".getBytes(),
       "Lgnu/classpath/Pair".getBytes(),
       "Lgnu/classpath/Pointer".getBytes(),
       "Lgnu/classpath/Pointer32".getBytes(),
       "Lgnu/classpath/Pointer64".getBytes(),
       "Lgnu/classpath/ServiceFactory".getBytes(),
       "Lgnu/classpath/ServiceProviderLoadingAction".getBytes(),
       "Lgnu/classpath/SystemProperties".getBytes(),

Obviously this is nasty if a class is added that needs protection.  We should
decide which of these should be protected and create an internal subpackage as
dalibor suggests.  Failing that, examples and tools both need to be moved
outside the gnu.classpath umbrella (which works for tools but not really for
examples).

The other issue is applying the protection at the Classpath level.  The VM
still needs to be able to extend this security.  JikesRVM protects its own
internal classes org.jikesrvm and org.mmtk as well.  Is it worth moving part of
the solution to Classpath, given the VM must do something anyway?
