RMI not working on Sun4.1.3

[Amitabh Arora]

When I try to run the following java code, I get the following crash.  Kaffe is
running on Sun 4.1.3 OS.

Please please please... I need some help on this one fast.  If I cannot make
it run on the sun4 then I cannot use Java at all, since 50% of our clients are
on this platform.

Does anybody had any other peculiar problem related to the Sun4.1.3
version of Kaffe?

Thanks. -amitabh arora
