Can someone explain to me why "java foo.class" has to fail with an
obscure error? (You're not suppoed to specify .class) Jeez.
if (!strcmp(".class", x+strlen(x)-6)) {
if (fixit) x[strlen(x)-7]=0;
else if (prettyerror) printf("Don't specify .class");
else {
obscure();
}
}
Can we at least have kaffe and friends give a pretty message?
Justin

I think it's probably something to do with '.' being the namespace
separator, and you could in theory have wanted foo/class.class ... but I
agree that a special-case check would alleviate a lot of confusion.
(I suspect you'd want it only on the command line, not elsewhere classes
are loaded. I have no idea if that's conveniently doable.)

While SomeClass.class is indeed a valid expression, it refers to the
class object of an instance. But as far as I can tell,
SomeClass.class can never denote a class because "class" is a keyword.

Good call. My Java is rusty (for which I am to some extent grateful).
