Jetty 9 is at End of Community Support.

Does this happen to you on Jetty 10 or Jetty 11?

@halibobo1205 that is a weird looking stacktrace, are some parts missing? Can you describe how you are running jetty (standalone, embedded, etc etc), any particular configuration you have, what kind of request it was handling at the time, any logs around that time etc. Preferably a small project that reproduces the problem. Need more info.

It looks like shadowserver is doing a scan visit, which happens once a day.
org.eclipse.jetty:jetty-server:9.4.11.v20180605 is OK.

@halibobo1205 what is the url of these requests? The only thing I can see in the code is that if there's something wrong with the url or maybe the request then we might return null for HttpServlet.getRequestURI when the SessionHandler is looking for the JSESSIONID on the url (because there is no JSESSIONID present as a cookie). Presenting the full request with headers etc would be helpful.

I have seen the same exception in our logs. Thanks for the log @halibobo1205, using this snippet it's trivial to reproduce the NPE against an embedded Jetty running in Spring Boot locally on port 8080:

echo 'CONNECT www.shadowserver.org:443 HTTP/1.1

' | nc localhost 8080

Thanks, the log from @halibobo1205 was very informative. Investigating now. However remember that, if you're using jetty-9.4 that is EOL, so I'll be fixing the NPE in jetty-10 onwards.
