Hello,
I have the following singleton:
@Singleton
@Startup
public class Workflow implements WorkflowIF {
private static Logger logger =
Logger.getLogger(Workflow.class.getName());
//some code here
@PreDestroy
public void cerrar(){
System.out.println("Gestor de Workflows parado");
logger.info("Gestor de Workflows parado");
}
Singleton works ok at @PostConstruct, but when doing shutdown in tomcat, it
gets a nullpointerexception in logger.info line of @PreDestroy. After that,
it also appear other errors...
