java.io.Closable automatically gets a PreDestroy hook

[rbygrave]

Currently we don't do this. For myself this does not seem intuitive. (Noting Micronaut DI also does not do this).

@Singleton
public class ShouldCloseAuto implements Closeable {


  /**
   *  Treated as a PreDestroy method
   */
  @Override
  public void close() {
    ...
  }

 
}
