> Issue Type: Bug
> Components: Collection
> Affects Versions: 4.4
> Reporter: noname713705
> Priority: Major
>
> When using {{CollectionUtils.filter(..)}}, if the passed collection is initialized with jdk {{Collections.singleton(..)}} and only contains an {{isBlank(..)}} string, the method will throw an exception instead of removing blank items as expected. Tested with commons-collections:4.4 and java8
