Sorry, there's not enough information in the log file to say.   One 
thing to do is to call System.out.println in places you expect to be 
called in order to follow the execution of the simulation.   As you add 
more, you'll eventually bound the conditions of the failure to the point 
you can see the failing code.  Chances are it will be some uninitialized 
target object, a bad method name, or the like.   Using a Java debugger, 
or even gdb (a native code debugger) is another way to control the 
program's execution, but following either can be confusing as the 
simulator is issuing your methods via native calls.  Compiling java code 
is quick, so it isn't that cumbersome just to keep changing 
instrumentation and iterating until you find the information you need.
