Issue when loading model

[yiluansong]

Hi, I really like the idea of this work and would like to try it out. I have installed Mallet. However, when I tried to load the pretrained classifier, I got the error below:

Exception in thread "main" java.lang.IllegalArgumentException: Problem loading classifier from file trained_prediction_model_mallet: java.rmi.dgc.VMID cannot be cast to java.util.UUID
at cc.mallet.classify.tui.Csv2Classify.main(Csv2Classify.java:93)

Do you happen to know how I can resolve this problem? Thank you!
