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.

<![CDATA[
public class ConcurrentApp {
public void getMyInstance() {
Map map2 = new ConcurrentHashMap(); // preferred for use with multiple threads
}
}
]]>
</test-code>
Thanks!
This will be fixed with PMD 5.3.2 and later.
