This is the full response: --- HTTP/2 does not strictly require HPACK support, but HPACK is a critical component of the HTTP/2 protocol for efficient header compression. HPACK is used to reduce the overhead of sending headers in each HTTP/2 request and response, which helps improve the performance of the protocol. In the context you mentioned, the HTTP client library (Jetty HTTP client) likely relies on HPACK for header compression when making HTTP/2 requests. If the HTTP client library is missing the http2-hpack JAR or is not properly configured to use HPACK, it can lead to issues like timeouts and inefficient header handling. So, while HTTP/2 technically can be operated without HPACK, it's highly recommended to have HPACK support for proper functioning and optimal performance.

There is still not enough information to work with. With the scant information you have provided, there are tens of thousands of possible setups and even more use cases for your scenario. Out of our 35,800 test cases, we don't have one that produces what you are describing. We need far more details, an open issue, and perhaps logging at debug level (of the entire request from receive, parsing, processing, response commit, response write, to error) would help. But a reproduction case would be most useful.

Hi Joakim, Actually it is not very complicated, apart from my setup being an embedded Jetty 12.0.x (ee10, http/2). I do not know what a callback is in this context and therefore I do not know where to start looking for what I am doing wrong. The application receives a HTTPS POST request that is sent from inside a page using an async XMLHttpRequest. The handling code processes the application specific payload and returns a similarly encoded response. That is when the warning is printed to stderr. It could be something in my embedded server setup code. Or it is an error in the way the application wraps requests/responses when forwarding them to the generic application level. Perhaps holding on to request or response objects too long or something similar. Blocking.Callback incomplete is a bit generic. Any explanation of what the warning hints at would be helpful to figure this out. Previous experience indicates that whenever Jetty issues an error or warning I am doing something wrong. But this is a new phenomenon that I never witnessed until 12.0.1 so I was hoping it might be something obvious.

Re: [jetty-users] Exception in Jetty 12.0.1
Silvio, This looks like a url with the sessionid encoded in the url, but it is incomplete. It looks like the url just contains JSESSIONID, whereas it should be JSESSIONID=. I don't think we changed the way we parse the sessionid from the url since at least jetty 10, but I could be wrong, I don't have my computer in front of me. Will look into it.
