I have the following issue and I would like to know what exactly happens. I am using Java\'s ScheduledExecutorService to run a task every five minutes. It works very well. E

This man had the same problem.

His solution is to catch Exception inside the runnable and re throw an RuntimeException:

try {
       theRunnable.run();
    } catch (Exception e) {
       // LOG IT HERE!!!
       System.err.println("error in executing: " + theRunnable + ". It will no longer be run!");
       e.printStackTrace();

       // and re throw it so that the Executor also gets this error so that it can do what it would
       // usually do
       throw new RuntimeException(e);
}
