---------------------------------------------
Summary: private constructors in utility classes break existing
code
Key: COLLECTIONS-519
URL: https://issues.apache.org/jira/browse/COLLECTIONS-519
Project: Commons Collections
Issue Type: Bug
Affects Versions: 4.x
Reporter: Radoslav Paskalev
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
