Hi All, I'm just getting started with the Rest High Level Client (5.6.0), and I'm having trouble shutting down my tomcat (8.5) instance because of unhandled threads. I _think_ it's related to the async IO threads for the HTTP connections, but I can't figure out how to stop them. I was hoping for a client.close() function or something, but so far, no dice. How do I stop dispose of the client and free it's resources once I'm through using it? ry ---

I've stumbled upon a workaround: keep a handle to the RestClient used to create the High Level Client, and close that when done. This seems to be working for me. ---
