> The {{KafkaProducer}} is not properly joining the thread it creates. The code is like this:
> {code}
> try {
>     this.ioThread.join(timeUnit.toMillis(timeout));
> } catch (InterruptedException t) {
>     firstException.compareAndSet(null, t);
>     log.error("Interrupted while joining ioThread", t);
> }
> {code}
> If the code is interrupted while performing the join, it will end up leaving the io thread running. The correct way of handling this is a follows:
> {code}
> try {
>     this.ioThread.join(timeUnit.toMillis(timeout));
> } catch (InterruptedException t) {
>     // propagate the interrupt
>     this.ioThread.interrupt();
>     try { 
>          this.ioThread.join();
>     } catch (InterruptedException t) {
>         firstException.compareAndSet(null, t);
>         log.error("Interrupted while joining ioThread", t);
>     } finally {
>         // make sure we maintain the interrupted status
>         Thread.currentThread.interrupt();
>     }
> }
> {code}
