    synchronized (lock) {

    }
  }
}

// Untrusted code
SomeObject someObject = new SomeObject();
someObject.lock.wait();

Untrusted code that has the ability to create an instance of the class or has access to an already created instance can invoke the wait() method on the publicly accessible lock, causing the lock in the changeValue() method to be released immediately. Furthermore, if the method were to invoke lock.wait() from its body and not test a condition predicate, it would be vulnerable to malicious notifications. (See rule THI03-J. Always invoke wait() and await() methods inside a loop for more information.)
