To work out if it's your use of the ProducerTemplate, try the following
route instead and see whether the leak persists:
from("timer://foo?period=1000")
.transform().constant("/home/_username_/some_temp_script.sh")
.to("ssh://_remote.machine.url.here_?username=_username_&keyPairProvider=#keyPairProvider")
.log("Received: ${body}");

I did write a simple app using Spring Boot (1.2.7.RELEASE) and Apache Camel
(2.15.0). The app is simple and has only 1 route: a timer will invoke a
method on a bean every 1s. The method invoked will use ProducerTemplate to
ssh into a remote machine, execute a small script, and print out the output
to the console. Simple, right?
However, when profiling this, I can see the number of threads! It seems like
any threads created for the ssh are never killed, but parked instead.
Because of that I run OOM pretty quickly with an error:
Exception in thread "Thread-341" java.lang.OutOfMemoryError: unable to
create new native thread

I think this is a bug, as from the documentation I can't see that I am using
the ProducerTemplate wrongly.
Or am I? If so, please tell me. If I am doing things right and it seems like
a bug, I will submit it...
