UML Sequence diagram for shutdown process

[CSchoel]

I would like to see something like an UML sequence diagram for the shutdown process that...

• shows all methods that are being called starting from the user input in the console client,
• highlights all LSP remote procedure calls with a color of your choice,
• and has a "lifeline" for each (relevant) thread on the server and/or client and clearly shows when this thread exits.

If my overview is correct, we should have the following threads:

• server-side
  • server main thread (main())
  • server thread listening for new clients (spawned in LaunchServer(), running in executor)
  • "stop" thread for the server (stopFromConsole())
  • a shutdown thread for each client running in CompletableFuture.supplyAsync within launchServer
  • Note: This is a questionable way to start a new thread, especially since you already have a thread pool names executor, that in which the new thread could be executed.
  • a listening thread for each client spawned by sLauncher.startListening() and running within executor
• client-side (console client)
  • client main thread (main())
  • listening thread that receives and handles messages from the server, spawned with cLauncher.startListening(), running in executor
• separate OMC process spawned by omc-java-api
  • here we are not interested about any internal threads, but just want to know if and when the OMC process itself is shut down

We should have one diagram for each shutdown-like command line options (option 89 and option 99). For simplicity, you may visualize synchronizations through a CompletableFuture or similar shared objects as message that is directly sent from one thread to another.

The Shutdown UML Shutdown Diagram can be found here. It still misses the thread started here. Furthermore it only shows the FullShutdownProcess.

Moved this Issue from "In Progress" to "Active Sprint" so I can work on other Issues and take a little distance from the topic to return to it at another time more open minded :)
