Just managed to successfully reproduce a j.l.AssertionError in ResponseSubscribers.HttpResponseInputStream.read(), which happens with Java 11, but not with 17 or newer.

A reproducer is in this public repo on GitHub:
https://github.com/snazy/http-client-tcp-reset-repro.git
The command `./gradlew test` using Java 11 can be used to reproduce the AE.
