    which has access to all classes and all fields, regardless of
    language restrictions. See MagicAccessor. </P>

    <P> This class is known to the VM; do not change its name without
    also changing the VM's code. </P>

    walks up the stack. The assumption is that the only such methods
    that will persistently show up on the stack are the implementing
