[jetty-users] Problem with a key for HTTP/3 in Jetty server

[Michał Niklas <michal.niklas@xxxxxxxxxx>]

Hi,



I have a server which use Jetty HTTP/2. Now I want to add support for 
HTTP/3 so I added:



	http3_connector = new HTTP3ServerConnector(jetty_server, 
sslContextFactory, new HTTP3ServerConnectionFactory(httpConfig));

	int http3_port = port_http2 + 1;

	http3_connector.setPort(http3_port);

	...

	SSLconnector = new ServerConnector(jetty_server, new 
ConnectionFactory[] { ssl, alpn, http2, http });

	jetty_server.setConnectors(new Connector[] { SSLconnector });

	jetty_server.addConnector(http3_connector);



In this code `sslContextFactory` and `httpConfig` are the same as for 
HTTP/2. But when I start server I got:



	java.lang.NullPointerException: Cannot invoke 
"java.security.Key.getEncoded()" because "key" is null

It starts HTTP/3 but not HTTP/2 and when I try to use port 18444 it 
rejects my queries.



	[mn:~] $ netstat -lnp  | grep 11818

	...(no HTTP/2 port)

	udp6       0      0 :::18444                :::* 
         11818/java



When I comment:



	SSLconnector = new ServerConnector(jetty_server, new 
ConnectionFactory[] { ssl, alpn, http2, http });

	jetty_server.setConnectors(new Connector[] { SSLconnector });

	// jetty_server.addConnector(http3_connector);



My server starts with HTTP/2 and works normally.



Is there something wrong with my JKS that it can work with HTTP/2 but 
cannot with HTTP/3? Is there an issue in my code?
