I totally agree.  Btw, there is one interesting detail: JavaDoc of 
Collections.synchronizedList() and the other synchronized*() methods 
explicitly state that the mutex used for synchronizing is that of the 
returned object:

http://docs.oracle.com/javase/7/docs/api/java/util/Collections.html#synchronizedList%28java.util.List%29

No such statement is done about Vector.  So while the source code of 
Vector tells us that the Vector instance is used to synchronize the 
JavaDoc does not give any guarantee about that and - at least 
theoretically - Sun/Oracle could change that and synchronize on another 
instance.

Kind regards
