java.util.concurrent.locks.Lock offers far more powerful and flexible locking operations than are available with synchronized blocks.
So synchronizing on a Lock throws away the power of the object, and is just silly.
Instead, such objects should be locked and unlocked using tryLock() and unlock().


Noncompliant Code Example

Lock lock = new MyLockImpl();
synchronized(lock) {  // Noncompliant
  //...
}


Compliant Solution

Lock lock = new MyLockImpl();
lock.tryLock();
//...
