The plan is to release 4.1 once COLLECTIONS-464 and COLLECTIONS-508 are
resolved which should not take too long anymore.

> private constructors in utility classes break existing code

> Key: COLLECTIONS-519

> Fix For: 4.1

> Hello,
> In collections version 4.x all utility classes (example ListUtils, MapUtils,
> PredicateUtils....) have private constructors. I consider this to be a
> serious bug, as it breaks any possibility the classes to be extended by the
> users. The javadoc says that constructors are private in order to prevent
> class instantiation but this object instantiation is not really problem and i
> think it is more important to allow classes to be extended. The possibility
> to extend utility classes was one of the major selling points of commons.lang
> and commons.collections projects. In the latest commons.lang project the
> utility classes still have public constructors.
> Best Regards
