Empty 'synchronized' statement
Reports synchronized statements with empty bodies.
Empty synchronized statements are sometimes used to wait for other threads to release a particular resource. However, there is no guarantee that the same resource won't be acquired again right after the empty synchronized statement finishes. For proper synchronization, the resource should be utilized inside the synchronized block.
