> The CachingNaiveBayesClassifier gives different results than the
> SimpleNaiveBayesClassifier. This is due to the fact that the
> CachineNaiveBayesClassifier does not calculate the log prior on the class
> (category) names, as it should.
> This bug has been fixed, and a patch has been attached to this issue.
> This affects master, as well as previous releases up to version 6.4.
