Unfortunately this isn't true anymore. gcj is part of GCC and 2MB is
not enough space.

(just MIPS) The default runtime requirements have grown since the early
days. 8MB appears to be a very comfortable amount of space, although
with some experimentation this could probably be brought down.

Yes, I agree that this is a bug, which is why I filed a case against it.
