Re: [jetty-users] BadMessage 400 Unknown Version
Your HTTP clients are not sending the required (per spec) HTTP version in their request headers.

Capture your HTTP traffic (in something like wireshark) and post the full request portion of your transaction.

Another cause of this are non-http clients that connect to your server send something meaningless and disconnect.
Which is common on the public internet, with people (and bots) probing your systems.
