Yes. Exactly. I forgot that, and I apologize :).

As said, this *is* very interesting. Btw, I decided to test IBM's JDK
1.4.1 also and it runs similary the original NBIO's install test as
Sun's JDK 1.4.
So, the fundamental question seems to be that do we want that Kaffe
respects JLS's (obsolete?) defintions, or non-open source implementions'
functionality (i.e. a "standard" functionality, not only Sun, IBM also)?
Also, I think it's a unfortunate that Java language doesn't have a
standard which would compel non-open source communities to respect the
standard. IMO, if there was a Java standard, it's possible that we never
had this discussion ;).
Finally, are you aware of this:
