Hi

Robert Schuster came up with the great idea that we have missed to
enable softfloat when building cacao + openjdk and it are quite likely
that we are building cacao with enabled VFP intructions that your armv5
hardware do not have.

It would be great if you could try to apply this patch on your oe.dev
tree and see if it fixes your problem.

Thanks,
Xerxes
