2020-08-10 14:36:12 ERROR Context:110 - This error has been corrected for, but doing this makes your app less robust.
2020-08-10 14:36:12 ERROR Context:111 - You should use Context.propagate() or a ContextPropagatingThreadFactory.

Although these are actually only informative (at this point) the underlying issue needs to be fixed.
