> 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
> Assignee: Benedikt Ritter
> Fix For: 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
> # offset1 < 0
> # offset2 < 0
> # len < 0
> # offset1 > offset2
> # offset1 > array.length
> # offset2 > array.length
> # offset1 + len > array.length
> # offset2 + len > array.length
