How interesting that this issue suddenly pops up in every VM
implementation at the same time. It is actually a bug in the VM that is
triggered by the fact that older byte code compilers added extra methods
to abstract classes when they implemented interfaces but didn't declare
the methods. It was workaround for old Sun VMs, but since Sun fixed the
bug in their VM the "workaround" is no longer emitted by compilers.

And yes, I just tested the Kissme VM and it seems to have the same issue
