Description

StringUtils.split does not behave correctly when the split is to be performed on word boundary characters ("\b"). Steps to produce the bug:

String string = "foo<bar>foofoo";
String[] st=StringUtils.split(string, "\b");

Expected o/p:

foo
<
bar
>
foofoo

 

Actual o/p:

foo<bar>foofoo

The issue seems to be with how zero-width separators are being handled. Note that Java library's String.split gives the expected output.

Thanks.
