Does Klasses.jar use 'sun/io/...'? (was: Patch for SunOS 4.1.3 build of 1.0.b2)

[Kiyo Inaba]

If I remember correctly, kaffe-1.0 becomes GPL'ed.
Which means, Klasses.jar (and pizza.jar) does not rely on Sun's class file.
Is my understanding correct?

If so, I understand 'compiling java with pizza' does not invoke any methods
in './sun/io/CharToByteDefault.class'. Am I right?
