I have the Rest Service example running, added actuators, see live hovers in the editor. While seeing that, I add a new private field, add a value annotation, running content-assist in the value parameter, all that works fine.

Then, I delete the code around the new private field and an unused import warning shows up. Everything seems to be fine up to here. Then I do an "organize imports" and after that, the green hovers seem to be totally off and a never-ending background job appears Language Server Background Job.

I can cleanup the situation in the editor again when typing into the editor (after the next keystroke, the green liver hover highlights are perfectly fine again), but the background job is still sitting around.

I think we need to investigate and fix both issues here.
