Hi All,

FYI, JamVM implements the version with the ProtectionDomain natively,
as suggested in the comments.  I also implement getPrimitiveClass
natively with a type char, rather than relying on the Java method that
converts it to a string (e.g. D->double).  This method is also marked
as destined to be removed.

Would it be a good idea to tidy up both at the same time?  Of course,
the class would still need modifications by the runtime because
loadClass/getResource, etc. are stubs which must be implemented.


P.S.  I'm going by the Classpath-0.10 release snapshot, and not CVS.
