Nothing. Since the thread already owns the monitor, the second synchronization will have no effect.

Or, to put it another way, the *first* synchronize statement will force the thread to wait for the monitor for this object. Once it has it, it will continue executing. The *second* synchronize statement will never cause a block, because it already has the monitor for this object.
