Nope. And I finally found out why. InvokeInterface was compiled by
gcj -C but my test program by jikes (1.18). And when InvokeInterface is
compiled with jikes then it fails also when run with gij!

What was happening was that jikes cleverly makes sure that the interface
is never initialized. While gcj -C just gets us a initialized class when
using the I.class construct.

The attached Test program does the same. And does fail with gij (CVS),
but not with gij 3.4 (which wrongly initializes the interface I when the
array is created). I'll add something like this to Mauve since I saw
that more runtimes get this wrong.

Cheers,

Mark
