我有一个带有标记为@Schedule的cron作业的java应用程序，java版本是
java version "1.7.0_51"
OpenJDK Runtime Environment (rhel-2.4.4.1.el6_5-x86_64 u51-b02)
OpenJDK 64-Bit Server VM (build 24.45-b08, mixed mode)
我在jboss7.1上运行应用程序
我们已经将机器的系统时间改了两个小时，基本上没有安装ntp，我们安装它来纠正时间，因为它已经过时了。
之后，cron作业停止工作。即使我重新启动jboss也无济于事。
日志中也没有错误可能表明出现了问题。我在代码中添加的System.out也没有写入输出，所以我认为代码根本没有执行。
我的cron工作：
@Singleton
@Lock(LockType.READ)
public class InstanceUpdater {
@EJB
FourPmInstanceBL fourPmInstanceBL;
@EJB
VMWareHandler vmWareHandler;
@EJB
PuppetHandler puppetHandler;
@EJB
FourPmInstanceHandler fourPmInstanceHandler;
@Inject
private Event<InstanceStatusChangeEvent> instanceStatusChangeEvent;
@Schedule(hour="*", minute="*", second="*/10")
public void startTimer() {
System.out.println(">>>>>>>>> Instance updater started " + new Date());
for (FourPmInstance instance : fourPmInstanceBL.getInstanceToProcess()) {
Date currentTime = new Date();
boolean canAcceptInstance = true;
//neaded 30 sec delay betwen acceptance because of vmware cocnurent template reading problem.
if(instance.getProcessAt() != null){
canAcceptInstance = currentTime.after(instance.getProcessAt());
System.out.println(">>>>>>>>> Instance can be accepted: " + canAcceptInstance);
System.out.println(">>>>>>>>> Proces instance at " + instance.getProcessAt());
}
//Long instancesInProgres = fourPmInstanceBL.getCountinProgres();
if (instance.getStatus().equals(InstanceStatus.NEW)) {
if(canAcceptInstance){
System.out.println(">>>>>>>>> Instance accepted " + instance.getName());
try {
instanceStatusChangeEvent.fire(new InstanceStatusChangeEvent(instance,InstanceStatus.IN_PROGRESS));
fourPmInstanceHandler.registerNewInstance(instance);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
instanceStatusChangeEvent.fire(new InstanceStatusChangeEvent(instance,InstanceStatus.ERROR));
}
}
} else {
try {
instanceStatusChangeEvent.fire(new InstanceStatusChangeEvent(instance,InstanceStatus.IN_PROGRESS));
System.out.println(">>>>>>>>> Instance update " + instance.getName());
fourPmInstanceHandler.updateHardwareAndLicence(instance);

e.printStackTrace();
instanceStatusChangeEvent.fire(new InstanceStatusChangeEvent(instance,InstanceStatus.ERROR));
