Hello @beradrian,
sorry for being so oblivious. Yes it would be best to create a separate PR
for this issue. I've already created a new jira issue for tracking this:
https://issues.apache.org/jira/browse/LANG-1122
> 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
