             Summary: Jetty server does not start up when a keystore with multiple certificates is used
                 Key: NIFI-7730
                 URL: https://issues.apache.org/jira/browse/NIFI-7730
             Project: Apache NiFi
          Issue Type: Bug
            Reporter: Kotaro Terada
            Assignee: Kotaro Terada


In the newer Jetty version (which is recently upgraded on the main branch), Jetty's `SslContextFactory()` has been deprecated, and we can use `SslContextFactory.Server()` or `SslContextFactory.Client()` instead. If we use `SslContextFactory()`, Jetty server does not start when we use keystores with multiple certificates, with the following error log.

In addition to that, we can remove `setEndpointIdentificationAlgorithm(null);` since it will be executed in the constructor of `SslContextFactory.Server()` if we replace with it.
 (See: [https://github.com/eclipse/jetty.project/blob/jetty-9.4.26.v20200117/jetty-util/src/main/java/org/eclipse/jetty/util/ssl/SslContextFactory.java#L2204])
