           Summary: StringUtils.splitByWholeSeparator ignores empty items
           Product: Commons
           Version: 2.1 Final
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Lang
        AssignedTo: commons-dev@jakarta.apache.org
        ReportedBy: leif.hanack@t-systems.com


I propose to create an additional set of splitByWholeSeparator methods that
would preserve separators. The functionality would be:

For an input string of "a::b::::d" and a separator "::" the return array would be
array[0] = "a"
array[1] = "b"
array[2] = ""
array[3] = "d"

Furthermore i think it is inconsequent when using the current
splitByWholeSeparator, that "a::b::" returns
array[0] = "a"
array[1] = "b"
array[2] = ""  <---

where as "a::b::::d" returns
array[0] = "a"
array[1] = "b"
array[2] = "d"

TIA
