Getting NotImplementedException in SolutionModel.java while using Trainer.run

[h44rd]

The following is the trace of the error:

Exception in thread "main" sun.reflect.generics.reflectiveObjects.NotImplementedException
	at edu.berkeley.compbio.jlibsvm.SolutionModel.writeToStream(SolutionModel.java:109)
	at edu.berkeley.compbio.jlibsvm.binary.AlphaModel.writeToStream(AlphaModel.java:140)
	at edu.berkeley.compbio.jlibsvm.binary.BinaryModel.writeToStream(BinaryModel.java:287)
	at edu.berkeley.compbio.jlibsvm.SolutionModel.save(SolutionModel.java:96)
	at Trainer.run(Trainer.java:66)
	at detectSpoof.main(detectSpoof.java:67)

Any help or a fix would be much appreciated.
