I don't believe the synchronized(this){} block is entirely meaningless. Essentially it acts as a gate where execution will halt until all other synchronized(this) blocks are complete before continuing. That's not to say another concurrent access can't sneak in between the block and the next statement, of course, but it does change the behaviour somewhat. But I can't really think of a use case. As a side effect, it may also act as a memory barrier.
