public class SynchronizedRestarter extends java.lang.ObjectA class that handles restarts of components via multiple threads. Specifically, if a component needs to be restarted and several threads may demand a restart but only one thread should be allowed to restart the component, then use this class. What this class guarantees is that several threads may come in while a component is being restarted, but they will block until the restart is complete. This is different from other techniques in that:
- A simple compare-and-swap to check whether another thread is already performing a restart will result in the requesting thread returning immediately and potentially attempting to use the resource being restarted.
- A synchronized method or use of a lock would result in the thread waiting for the restart to complete, but on completion will attempt to restart the component again.
