The ArffDataSetReader initializes all instances with null labels when reading an arff file.

The error ends up looking like this

Running Random Hill ClimbingException in thread "main" java.lang.NullPointerException
	at shared.SumOfSquaresError.value(Unknown Source)
	at opt.example.NeuralNetworkEvaluationFunction.value(Unknown Source)
	at opt.example.NeuralNetworkOptimizationProblem.value(Unknown Source)
	at opt.RandomizedHillClimbing.<init>(Unknown Source)
	at tests.OptdigitsTest.main(Unknown Source)
