Java ReentrantLock Concurrency Issue

Consider the LockExample class shown below. What is the most likely concurrency issue to result from the omission in the doWork method?

import java.util.concurrent.locks.ReentrantLock;

public class LockExample {
    private ReentrantLock lock = new ReentrantLock();
    
    public void doWork() {
        lock.lock();
        try {
            // perform operations
            doMoreWork();
        } finally {
            // Missing unlock here
        }
    }
    
    public void doMoreWork() {
        lock.lock();
        try {
            // additional operations
        } finally {
            lock.unlock();
        }
    }
}
