> I am running into an issue with line 156 of ClientPushH2StreamHandler. The method updateInputCapacity() is being called and exchangeHandler is null, resulting in an IllegalStateException.
> This logic is quite deep in the HttpClient so I have no idea what I am dealing with. Any possible ideas on why this would happen? I see that the exchangeHandler is initialized in consumePromise, but updateInputCapacity is being called before that resulting in the field being null still.
> I can potentially provide a project to reproduce the issue, but that would take some effort because this is happening deep within my own company's product, and so I would have to take some time to determine what minimal amount of logic is needed to actually cause the issue.
> I was hoping maybe someone can provide some initial insight into the issue before I do that.
