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.
