> Key: COLLECTIONS-453
> URL: https://issues.apache.org/jira/browse/COLLECTIONS-453
> Project: Commons Collections
> Issue Type: Bug
> Affects Versions: 3.2.1
> Reporter: Thomas Neidhart
> Fix For: 4.0
>
>
> Several classes (e.g. SwitchTransformer) take in their constructor an array
> as input which is not copied/cloned.
> Thus its internal representation may be changed externally.
> The corresponding factory methods *do* copy the input arguments thus we have
> two choices:
> * move the copy from the factory methods to the ctors
> * make the ctors private to prevent their use
