Dummy implementations that do nothing are a really bad thing, I agree. But a
dummy implementation that either returns with the correct result or throws a
NYIException makes it clear to the user what had happened.
Currently, we have those dummy methods anyway - and can't get rid of them,
because some methods are partly, but not completely, implemented. With a new
Exception class, the gcj linker could stop with an error message when such a
method is instantiated and thrown. If we abuse any existing JDK Exeption for
it, this would not be possible.
Cheers,
Andy.
