Like Simone said, file an issue.

Please provide as many details as possible, a reproducer is ideal!

This is way out of scope for what the jetty-users mailing list can handle.

We need to share code, share logs, collect data, etc.

There is something fundamentally wrong with the callbacks, but which ones? from where? How does the request flow through Jetty? How are you using Jetty? (code helps)

Hi Simone,

Well, in the process of collecting more details and trying to describe
the issue more clearly I discovered that I am delusional. The requests
are not blocked at all but some other error in my test setup prevented
them from being handled properly. I mistakenly concluded that the warning

WARN :oeju.Blocker:qtp686466458-43: Blocking.Callback incomplete

was in any way a result of the requests actually being blocked. Please
ignore my previous message about this.

I would however like to know what the warning means and why it is
manifesting itself now with 12.0.1. It is starting to clog my stderr-logs...

Thank you,

Silvio
