These aren't the same thing.  IcedTea wraps and expands OpenJDK7.

I'd be very surprised if you don't need more of the bsd work than just the network
stack.  What exactly have you ported across?

Why ZeroVM?  You mention above that the port is to x86 and x86_64, both of which 
have full HotSpot ports with a JIT.

No but given OpenJDK7 doesn't support *BSD, I'm not too surprised this doesn't
work, especially when you're also throwing zero into the mix.  Why not just
build with the bsd-port?  There's an option to do that, though it's not really
maintained as I don't know of anyone running IcedTea on *BSD.
