Quartz scheduler shutdown when two applications share Quartz from the same classloader in JBoss EAP 5

Issue

• We have two web applications running on JBoss 5.2.0 EAP Server Instance, each containing a quartz scheduler( Copied quartz-all-1.6.5.jar to JBoss Server Instance LIB directory) doing its own job. I have noticed that if one application is hot deployed, the quartz scheduler in the other application stops running. I would like to know if I am using an incorrect approach.

Below is the code sample used in the scheduler classes. The methods of this class are called from a Servlet Context Listener class or from Servlet's init/destroy methods.

public void startScheduler() {      
    schFac = new StdSchedulerFactory();
    try {
        scheduler = schFac.getScheduler();
        jobDetail = new JobDetail("job1", "group1", ExampleJob.class);
        simpleTrigger = new SimpleTrigger("scheduler1", "scheduler_group1");
        ...
        scheduler.scheduleJob(jobDetail, simpleTrigger);
        scheduler.start();      
    } catch (SchedulerException e) {            
        e.printStackTrace();
    } catch (Exception ex) {
        ex.printStackTrace();
    }
}

public void stopScheduler() {
    if(scheduler != null) {
        try {
            scheduler.deleteJob("job1", "group1");              
            scheduler.shutdown();
        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }
