> HARMONY-39 Pattern.split() method discards last trailing empty string when given pattern matches last symbol of input character sequence.
> The same problem appears if the input string is empty. JavaDoc says that if the expression does not match any part of the input sequence then the resulting array has just one element, namely this string. Thus in the case of empty input string one element array containing empty string should be returned, however HARMONY-39 Pattern.split() returns empty array.
> This problem also affects java.lang.String.split() method, because according to JavaDoc it uses Pattern.split() method.
> The following test demonstrates the problem:
> ",,".split(",", 3).length; //Resulted array will have two elements, while it should have three.
