#1342 UseConcurrentHashMap false positive (with documentation example)

[Rei Angelus]

If we declare an map with the interface Map by instantiate it with ConcurrentHashMap (such as the PMD documentation example), an "Use Concurrent Hash Map" error occurs.

Thanks!

This will be fixed with PMD 5.3.2 and later.
