Description
Currently quotes are not escaped in the Jetty request log. This is applicable for example to User-Agent field. User agents are not usually quoted but they could be, even maliciously to corrupt logs or break log processing scripts.
Also applicable to Referer field, or in fact any field that comes from the end user.

How to reproduce?
Executing this:
curl -A 'My Quoted " Agent' 'http://localhost:8080/'

Logs this in the user agent field in the request log:
"My Quoted " Agent"

The same on Apache logs this:
"My Quoted \" Agent"
