returns a stream with an empty string as the last element if we use an example from

http://download.java.net/jdk8/docs/api/java/util/regex/Pattern.html#split%28java.lang.CharSequence%29

Consider the following code:

-------------------
        Pattern pattern = Pattern.compile("o");

        System.out.println("splitAsStream(..) = " + Arrays.toString(pattern.splitAsStream("boo:and:foo").toArray()));
        System.out.println("split(..) = " + Arrays.toString(pattern.split("boo:and:foo")));
-------------------


The output will be

splitAsStream(..) = [b, , :and:f, ]
split(..) = [b, , :and:f]


The following JCK test will fail due to this
