Thanks, that helped us to trace down the root issue. We found that it was stopped from one of our own libs that is not direct part of our codebase. So it was our own fault!

We decided to keep the following snippet in our codebase to prevent that the httpclient is stopped in the future:

httpClient.addEventListener(new LifeCycle.Listener() {
    @Override
    public void lifeCycleStopped(LifeCycle event) {
        // prevent stopping of http client as it is used in various places
        var e = new RuntimeException("Don't stop me know!");
        try {
            httpClient.start();
        } catch (Exception ex) {
            // handle ex        }
        throw e;
    }
});

Thanks again and have a nice weekend!

Best,
Matthias
