Hi All, I am trying to use ALPN in Netty with OpenJDK 8u252. Apparently this version of openJDK has backported the Java 9 ALPN APIs so the Jetty ALPN stuff shouldn't be necessary.
According to https://github.com/jetty-project/jetty-alpn-agent "Starting with OpenJDK 1.8.0_252 the use of jetty-alpn-agent is not strictly required anymore since the standard ALPN APIs have been backported <https://mail.openjdk.java.net/pipermail/jdk8u-dev/2019-November/010573.html> to OpenJDK 1.8.0_252 from Java 9" However, when I try and start a Netty based server using OpenJDK 8u252 I get the following exception: java.lang.NoClassDefFoundError: org/eclipse/jetty/alpn/ALPN$Provider at io.netty.handler.ssl.JettyAlpnSslEngine.newServerEngine(JettyAlpnSslEngine.java:60) at io.netty.handler.ssl.JdkAlpnApplicationProtocolNegotiator$AlpnWrapper.wrapSslEngine(JdkAlpnApplicationProtocolNegotiator.java:141) at io.netty.handler.ssl.JdkSslContext.configureAndWrapEngine(JdkSslContext.java:360) at io.netty.handler.ssl.JdkSslContext.newEngine(JdkSslContext.java:330) I.e. the Netty code still seems to want to use the Jetty stuff. Any thoughts on how I configure Netty correctly so it doesn't look for the Jetty ALPN stuff when I know I'm using OpenJDK 8u252? So I guess this must be possible somehow. -- You received this message because you are subscribed to the Google Groups "Netty discussions" group.
