> These exceptions appears when app is started under load (small load, no
> benchmarks or whatever else).
> If problem arise then app can't be normally started. Exception is thrown each
> time. Seems like the internal state of CaseInsensitiveMap become broken.
> I will attach a patch for issue in several minutes.
