Simulator freezes when using Eclipse Run Configuration

The simulator freezes if you re-run a CIQ using a predefined Eclipse "run configuration", which would be handy for running your app with one click, if it worked. App settings may also be reset spontaneously.

Environment:
Eclipse 2018-09
Windows 10
CIQ SDK/plugin 3.0.4

Recreation:
1. Create simple data field project, with single target: e.g. 645. Make no changes
2. Run project normally.
3. While project is still running, run it again. Verify that the previous process is terminated and the new process runs smoothly
4. Close simulator

5. Create Eclipse "Run Configuration": Run > Run Configuration > Connect IQ App > New. Choose project and device, and press Apply
6. Run project
7. While project is still running, run it again using the new "run configuration". Eclipse will announce "'Stopping Launches' has encountered a problem. Terminate failed.' and the simulator will freeze

The apparent partial workaround is to kill the app/device before re-running the app, but it seems there's also some issues with settings being reset all the time when running like this.
