ClientJarMakerRegistry

public class ClientJarMakerRegistry extends Object
All client jar file are created in a separate thread when the client jar file is not requested at deployment time. These threads are registered in this singleton registry so that when client jar files are requested from the deployment clients, we check if the client jar file is not in the process of being created.
