> There is a race between the dispatcher thread and another thread closing a
> session. In the unlucky case, the dispatcher thread can die with an ISE as
> below.
> The issue appears to be that the Dispatcher#close method does not await the
> shutdown for the dispatcher before returning, so the Dispatcher may run on
> for another iteration whilst the dispatcher reference has been nulled.
> This appears to be a longstanding issue (the fixme goes back to 2007) and is
> showing up now owing to r1693225, which makes uncaught exceptions fail the
> test.
