InvalidValueChecker - 505 HTTP Version Not Supported from Jetty

[davide94it]

Description

Running the fuzz-lean I obtain an 505 error with unconsistent response from Jetty (HTTP/1.1 or HTTP/0.9 ?).

{
    "status_code": "505",
    "checker_name": "InvalidValueChecker",
    "reproducible": true,
    "verb": "GET",
    "endpoint": "/health-history",
    "status_text": "HTTP Version Not Supported",
    "request_sequence": [
        {
            "producer_timing_delay": 0,
            "max_async_wait_time": 20,
            "replay_request": "GET /health-history?page=1&size=1&sort=vu[MC\nr4Ci HTTP/1.1\r\nAccept: application/json\r\nHost: my-service\r\nRequestID: fdsfdsaer77909fds\r\nRequestDate: 2024-02-26T08:58Z\r\nUserID: USER100\r\nOriginalRequestDate: 2024-02-26T08:58Z\r\nImpersonatedUserID: OTHERUSER100\r\n\r\n",
            "response": "HTTP/1.1 505 HTTP Version Not Supported\r\nContent-Type: text/html;charset=iso-8859-1\r\nContent-Length: 65\r\nConnection: close\r\nServer: Jetty(11.0.18)\r\n\r\n<h1>Bad Message 505</h1><pre>reason: HTTP/0.9 not supported</pre>"
        }
    ]
}

Moreover, trying to replicate the request with curl I don't get that error from the server but rightly a 400 Bad Request.

curl --http1.1 --location --globoff 'http://localhost:8077/health-history?page=1&size=1&sort=vu[MC\nr4Ci' --header 'accept: application/json' --header 'RequestID: fdsfdsaer77909fds' --header 'RequestDate: 2024-02-26T08:58Z' --header 'UserID: USER100' --header 'OriginalRequestDate: 2024-02-26T08:58Z' --header 'ImpersonatedUserID: OTHERUSER100'

Steps to reproduce

I'm using a Docker container, here the steps that I perform:

1. clone project
2. build the Docker image from the root directory of the project docker build -t restler .
3. run the container docker run --rm -it restler
4. get the swagger.json from the server wget -O api-docs.json http://my-service:8077/v3/api-docs
5. compile ./Restler compile --api_spec api-docs.json
6. run fuzz-lean ./Restler test --grammar_file ./Compile/grammar.py --dictionary_file ./Compile/dict.json --settings /shared/config/user_settings.json --no_ssl

Expected results

No response
