Jonathan Ellis updated CASSANDRA-2061:
--------------------------------------

    Attachment: 2061.txt

As near as I can tell, an exception thrown on a scheduled task will never kill the executor, just like in TPE.  I don't remember why the author [me] wrote that code -- probably because it was replacing Timer and TimerTask, and an uncaught exception in a TimerTask _will_ kill the timer.

Patch removes RetryingSTPE and replaces with DebuggableSTPE that has an afterExecute copied from DTPE.

> {quote}Since you are using ScheduledThreadPoolExecutor.schedule(), the exception was swallowed by the FutureTask.
> You will have to perform a get() method on the ScheduledFuture, and you will get ExecutionException if there was any exception occured in run().{quote}
