As far as I know - No, it doesn't.

Please use jikes from testing distro (1.15). You shouldn't have any
other problems because of that. Bytecode outputed by newer
jikes makes use of some functions that SableVM doesn't have yet.

It's good question to the upstream when it will get that functions.
But I am am sure it's the no. 1 on the TODO list as soon as the author
gets back from his vacations.

BTW: I tested above example w/ jikes 1.15 (and jikes-sable wrapper
from current jikes package version) and it worked.
