The replace methods only result in an access of the entry if the value is replaced. The putAll method generates one entry access for each mapping in the specified map, in the order that key-value mappings are provided by the specified map's entry set iterator. No other methods generate ...

@mghildiyactually those methods are being used, these are kind of "magic methods" that Java knows to call during Java serialization/deserialization. Also I would recommend not extending hashmap to implement linked hash map, but maybe some of the hashtable code can be factored out for reuse....
