Is that really necessary? I mean, the bottom line is that if somebody
gets an unexpected exception they're going to look at the ASCII message
for the details, and this will show the realy problem either way. It
doesn't really matter what the class is.

On the other hand, if a human is not involved, then again it doesn't
matter what the class is..it's more important to do what Sun does.

IMHO being bug-compatible with Sun is both easier and ultimately
more successful for kaffe's 'customers' than trying to incompatibly
outsmart and/or engineer around deficiencies in their design.
