Your problem is that the request line ends with [space][cr][lf] when the
protocol requires that it end with [cr][lf].
Both Tomcat 8.5 and Tomcat 9 will fail with a similar error. Try it:
(With extra space)
$ echo "GET / " | nc localhost 8080
[response: 400 Bad Request]
(Without extra space)
$ echo "GET /" | nc localhost 8080
[response: 400 Not Found]
I just tested on 8.5 and this is how it behaves.
If you want to add Connection:close header (which is further invalid in HTTP
9.0, by the way), you can do:
(With extra space)
$ echo "GET /
Connection:close" | nc localhost 8080
[response: 400 Bad Request]
(Without extra space)
$ echo "GET /
Connection: close" | nc localhost 8080
[response: 400 Not Found]
You cannot "fix" this with Tomcat configuration. You are violating multiple
parts of the HTTP specification and Tomcat is properly refusing you because of
it.
