Almost exactly like putting the 'synchronized' keyword on a method, except will synchronize on a private internal
Object, so that other code not under your control doesn't meddle with your thread management by locking on
your own instance.
 For non-static methods, a field named $lock is used, and for static methods, $LOCK is used. These will be generated if needed and if they aren't already present. The contents of the fields will be serializable. 

Complete documentation is found at the project lombok features page for @Synchronized.
