What about adding a static instance counter variable to your class. Then you would need a synchronized method which increases the counter for each object created and create the log file name from that value. Something like this:

  private synchronized initLogger(){
     yourClass.cnt++;
     myJobid = yourClass.cnt;

     //include your logging code here
  }
}
