You don't say what architecture this is running on . It would be
helpful to know that. Also it would be nice to have a back trace from
the failure point.
It looks like you did something similar to making a call through a NULL
function pointer.
I don't want to sound discouraging, but I don't think much libgcj
porting work has been done for Nexenta. So if you want to get it
working, you may be spending a lot of quality time with gdb. Also I
would not rule out problems with the C library or linker as causes. But
really from the information you gave it is very difficult to say what is
wrong.
