> he org.jboss.system.server.profileservice.hotdeploy.HDScanner bean's setScanEnabled() method fails when setting to "true" if it was previously set to "false" When enabling, the setter calls the start():
>    public synchronized void setScanEnabled(boolean scanEnabled)
>    {
>       if (scanEnabled == true && activeScan == null && scanExecutor != null)
>       {
>          start();
>       }
>       else if (scanEnabled == false && activeScan != null)
>       {
>          stop();
>       }
>       this.scanEnabled = scanEnabled;
>    }
> However, if the scanEnabled member variable (this.scanEnabled) is false this call does nothing:
>    public void start()
>    {
>       if (scanEnabled)
>       {
>          activeScan = scanExecutor.scheduleWithFixedDelay(this, 0, scanPeriod, TimeUnit.MILLISECONDS);
>       }
>    }
