The simplest place is source code [1] [2]:
public static boolean knownMap(Object map) {
Class<?> cls = map == null ? null : map.getClass();
return cls == HashMap.class ||
cls == LinkedHashMap.class ||
(!wrapTrees() && cls == TreeMap.class) ||
cls == ConcurrentHashMap.class;
}
public static boolean knownCollection(Object col) {
Class<?> cls = col == null ? null : col.getClass();
return cls == HashSet.class ||
cls == LinkedHashSet.class ||
(!wrapTrees() && cls == TreeSet.class) ||
cls == ConcurrentSkipListSet.class ||
cls == ArrayList.class ||
cls == LinkedList.class ||
cls == SINGLETON_LIST_CLS;
}
