     [ https://issues.jboss.org/browse/WFLY-6681?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Alan Echer updated WFLY-6681:
-----------------------------
    Steps to Reproduce: 
I created a simple application to illustrate the problem, this is a normal behavior or is there any way to run treads in the background without disturbing the running web application?

{code:java}
import javax.ejb.Schedule;
import javax.ejb.Singleton;

@Singleton(name = "Schedule")
public class ScheduleTest {

    @Schedule(hour = "*", minute = "*", second = "30")
    public void enviaResumoSemanalContaUsuario() {
        System.out.println("Testing!");
    }
}
{code}

Place debug the lines of "Testing," and the web page stops responding.

{code:html}
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
  <head>
    <title>$Title$</title>
  </head>
  <body>
  $END$
  </body>
</html>

{code}
