title: I want to sort using commons-collections4-4.0 ComparatorChain
body: <p>When we use the latest commons-collections4-4.0jar, we get an error message as shown below regarding making a sort option with a usage of the ComparatorChain and the BeanComparator. Do you have any idea what's wrong with this?  We use commons-bean utile-1.9.2.jar for beanutils.</p>
