Empty synchronization blocks can have an effect as long as the object
being synchronized on is shared across multiple threads. As they would
be in this case.
You may be thinking of thread-local synchronization. If you do:
synchronized(new Object()) {}
That won't have any effect, because the object isn't shared across
multiple threads.
