      Since the former major LTS release I experience a kinda problematic problem with our Jenkins instance. Whenever the master is stopped (shutdown) with active connections to slaves, the JLNP client on the slaves stops working with the message: "Unable to launch the application". This was not the case before, so the client application was still running and reconnected once the master was back online.

      With the current behavior I have to step through all the >60 slave nodes, and start the JLNP client manually.

      Steps:
      1. Download Jenkins 1.580.1 and run it
      2. Setup a dumb slave via Java Web Start
      3. Connect the slave via the same machine
      4. Stop the master

      After step 4 the JLNP client should stay open, waiting for the master being online again. But it fails with the above message and the following stack:

      Exception:
