Anders Wallgren commented on HTTPCORE-29:
-----------------------------------------
It the IOException happens while initialiizing the reactor, I can see a
legitimate reason to shut down the reactor.
However if the reactor has started properly and I now have 250 outbound
sessions and one of them has an IOException, it doesn't make sense to me that
the other 249 sessions should have to fail. The session that had the problem
should be shut down, but the reactor should not fail.
Does that make sense?

> I'm trying to figure out what to do when DefaultConnectingIOReactor.execute
> throws an exception. It doesn't seem like I can just call execute() again
> after handling the exception, since that will recreate all the state in DCIOR.
> Seems to me that there needs to be a different way to handle exceptions, or
> the execute method should be callable more than once.
