Warning
The methods of ForwardingSortedMap forward indiscriminately to
the methods of the delegate. For example, overriding put alone will not change
the behavior of putAll, which can lead to unexpected behavior. In this case, you should
override putAll as well, either providing your own implementation, or delegating to the
provided standardPutAll method.
default method warning: This class does not forward calls to default methods. Instead, it inherits their default implementations. When those implementations
invoke methods, they invoke methods on the ForwardingSortedMap.
Each of the standard methods, where appropriate, use the comparator of the map to test
equality for both keys and values, unlike ForwardingMap.
The standard methods and the collection views they return are not guaranteed to be
thread-safe, even when all of the methods that they depend on are thread-safe.
