How to reproduce?

Configure Jetty with a AsyncMiddleManServlet and send a POST without a body.

[joakime]

Was your POST one with the Expect: 100-continue header or not?

A quick test of Jetty 10.0.11 (the currently supported minimum version of Jetty) using curl with a no-body POST (curl -X POST http://example.com, which does not produce an Expect: 100-continue) shows that it works.
