> Looking at {{okhttp3.logging-interceptor}}, its import-package is optional:
> {{okhttp3;resolution:=optional}}. I'm guess that means the bundle can start
> before {{okhttp3}} bundle has been wrapped/started (hence the class not being
> available).
> It's getting called during the bundle startup of
> {{io.fabric8.kubernetes-client}} because that bundle declares services.
> {{io.fabric8.kubernetes.client.utils.HttpClientUtils.createHttpClient:118}}
> references {{okhttp3.logging.HttpLoggingInterceptor}}, which triggers all
> this class loading.
> But later in the startup log, there's no mention of rewiring
> {{okhttp3.logging-interceptor}} (which I'd expect if {{okhttp3}} package
> subsequently becomes available.
> Requires further investigation!
