> Key: COLLECTIONS-389
> URL: https://issues.apache.org/jira/browse/COLLECTIONS-389
> Project: Commons Collections
> Issue Type: Bug
> Components: Collection
> Affects Versions: 4.0, 4.x
> Environment: Platform Independent
> Reporter: SHIN HWEI TAN
> Labels: javadoc, null
> Fix For: 4.0
>
> Original Estimate: 2m
> Remaining Estimate: 2m
>
> The Javadoc comment below states that the method "throws IllegalArgumentException if the map is null":
> /**
> ....
> * @param map the map to use to transform the objects
> * @return the transformer
> * @throws IllegalArgumentException if the map is null
> */
> public static <I, O> Transformer<I, O> mapTransformer(Map<? super I, ? extends O> map) {
> return MapTransformer.mapTransformer(map);
> }
> However, the method returns a NULL_INSTANCE object instead of throwing IllegalArgumentException when called with null.
> Suggested Fixes:
> 1. Change "@throws IllegalArgumentException if the map is null" and "@return" to "@return NULL_INSTANCE if the map is null".
> or
> 2. Remove the entire "throws IllegalArgumentException if the map is null".
