> Project: HttpComponents HttpCore

> Components: HttpCore
> Affects Versions: 5.1
> Reporter: Andy Wilkinson

> Fix For: 5.1.1, 5.2-alpha1

> I originally [reported|https://github.com/eclipse/jetty.project/issues/6164] this to the Jetty project but they have identified that the problem is in HttpCore's {{AbstractH2StreamMultiplexer}}. Jetty 10 has added support for {{SETTINGS_ENABLE_CONNECT_PROTOCOL}}. When consuming the settings frame, {{AbstractH2StreamMultiplexer}} consumes the code but, as it has no {{H2Param}} for it, it does not consume the value. This partial consumption results in an failure later on.
> The problem can be reproduced using [this sample project|https://github.com/wilkinsona/jetty-h2c-problem].
