Hello all,

I did a ejb with scheduler annotation, and then is working correctly, but every jboss as 7.1.1 final start i receive this error:

23:20:47,994 ERROR [org.jboss.as.ejb3] (MSC service thread 1-3) JBAS014129: Could not restore timer from C:\jboss-as-7.1.1.Final\standalone\data\timer-service-data\PortalAmil-EAR.PortalAmil-EJB.MailMDB\59970b97-5d5e-44ef-9700-8e7c826929e4: java.io.EOFException: Read past end of file

My EJB code with scheduler is:


import java.util.Calendar;
import java.text.SimpleDateFormat;
import javax.ejb.ConcurrencyManagement;
import javax.ejb.ConcurrencyManagementType;
import javax.ejb.Schedule;
import javax.ejb.Singleton;
import javax.ejb.Timer;
import javax.inject.Inject;
import org.jboss.logging.Logger;
 
 
 
 
@Singleton
@ConcurrencyManagement(ConcurrencyManagementType.BEAN)
public class MailMDB
{
          @Inject
          private Logger log;
 
          private void printData(Object message)
          {
                    if(log !=null)
                              log.debug(message);
                    else
                              System.out.println(message);
          }
 
 
          @Schedule(hour="*", minute="*/5", persistent=true)
          public void backgroundProcessing(Timer timer) {
  
                    final SimpleDateFormat dtFormat = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");
  
                    Thread t = new Thread(new Runnable() {
                              printData("Starting the thread: " + Thread.currentThread().getName());
                              //Do anything....
                              printData(Thread.currentThread().getName() + " - Thread Stop in " + dtFormat.format(Calendar.getInstance().getTime()));
                    });
  
                    t.setPriority(Thread.NORM_PRIORITY);
                    t.setName("Thread - " + dtFormat.format(Calendar.getInstance().getTime()));
                    t.start();
          }
}
