我正在尝试在 Java 8 上使用 Jetty 9.4.x 使用 SSL 部署 Http2 服务器。当客户端尝试与服务器建立连接时，我收到以下错误
java.lang.IllegalStateException: Connection rejected: No ALPN Processor for sun.security.ssl.SSLEngineImpl from [o.eclipse.jetty.alpn.conscrypt.server.ConscryptServerALPNProcessor@2814b525]
Java 11 不会出现此问题，它仅特定于 Java 8。
任何帮助将不胜感激。
根据文档jetty-alpn-conscrypt-server，我已包含org.conscrypt:conscrypt-openjdk-uber
https://www.eclipse.org/jetty/documentation/9.4.x/alpn-chapter.html#alpn-conscrypt
public class Http2Server {

server.start();
server.join();
}
public void init() throws Exception {

server.addConnector(connector);
ALPN.debug=false;
}
SslContextFactory buildSslContextFactory() throws Exception {
