-------------------------------------
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
