             Summary: Inconsistent behavior of swap for malformed inputs
                 Key: LANG-1122
                 URL: https://issues.apache.org/jira/browse/LANG-1122
             Project: Commons Lang
          Issue Type: Bug
          Components: lang.*
            Reporter: Benedikt Ritter
             Fix For: Patch Needed, 3.5


Following the discussion at https://github.com/apache/commons-lang/pull/47 we need to decide how malformed inputs should be handled by the swap method. We have to handle several forms of malformed inputs and we should decide how to do that based on the current behavior of ArrayUtils. Malformed inputs are:

* array == null
* array.length == 0
* start < 0
* end < 0
* offset < 0
* start > end
* start > array.length
* end > array.length
* start + offset > array.length
* end + offset > array.length
