    Thanks for the review @GJL. I've fixed the failing test case. Let's see what Travis says.

> The {{TaskExecutor}} does neither properly stop RM heartbeats nor does it check whether
a RM heartbeat timeout is still valid. As a consequence, it can happen that the {{TaskExecutor}}
closes the connection to an active {{RM}} due to an outdated heartbeat timeout.
