Please see the following post. I think it will help.
Looks like this package is experiencing bitrot from other changes to ECJ. In NSGA2Breeder.setup(), change the line
for (int i = 0; i < state.population.subpops.length; i++)
for (int i = 0; i < reduceBy.length; i++)
However it looks like the package is missing some default settings and also I don't like the look of the F2 problem. You can get the package working with the above, but it will take a few days for me to properly go through it and clean it out.
