I think as a practical matter it's a good idea to support some of
the more obvious flags like "-classpath".. however, full compatibility
is probably not worth the trouble.

Also, note that the specification for these flags is part of the
JNI invocation interface, and there is no specification (that I
know of) for the java(1) command line itself. Sun apparently just
copies over the command line flags into the JNI_CreateJavaVM() call,
which is why they look the same.
