I found another case where the servlet engine is creating TWO instance of an
application level variable. Here is the class:
public class Test implements Serializable, ServletContextListener{
ServletContext application;
public void contextInitialized(ServletContextEvent event) {
System.out.println(this + " - contextInitialized()"); //prints
memory address
this.application = event.getServletContext();
}
public void doSomething(){
System.out.println(this + " - doSomething()"); //prints DIFFERENT
memory address
application.getInitParameter("dsn"); //produces null pointer exception
}
public void contextDestroyed(ServletContextEvent event) {}
}
Should this print TWO memeory addresses?
