问题描述

我在Ubuntu 9.0.4上使用Java 12，JMeter 5.1.1，并在尝试发送HTTP/2请求时遇到以下异常:

I am using Java 12, JMeter 5.1.1 on Ubuntu 9.0.4 and bumps into the following exception when trying to send HTTP/2 request:

Response code: Non HTTP response code: java.util.concurrent.ExecutionException
Response message: Non HTTP response message: java.lang.IllegalStateException: No Client ALPNProcessors!

JMeter 5.1.1默认带有jetty-alpn-client-9.4.9.v20180320.jar.

JMeter 5.1.1 comes with jetty-alpn-client-9.4.9.v20180320.jar by default.

然后我从

I then download the jetty alpn java client library from http://central.maven.org/maven2/org/eclipse/jetty/jetty-alpn-java-client/ and put that into jmeter installed lib/ folder and results in this exception:

我切换到Java 11，但收到相同的错误. 任何建议和见识都将受到赞赏.

I switched to Java 11 but get the same error. Any advice and insight is appreciated.

推荐答案

解决方案:下载

Solution: Download http://central.maven.org/maven2/org/eclipse/jetty/jetty-alpn-java-client/ and put in the installed jmeter lib/ folder. JMeter only comes installed with jetty-alpn-client which is not enough.
