HTTP/2 Request with JMeter fails with “nullSession” (jetty-alpn)

问题


I've installed the Blazemeter HTTP/2 Plugin for JMeter and have trouble getting HTTP/2 requests to work.

My minimal test looks like this:

  • Thread Group
    • HTTP2 Request
      • Server: stackoverflow.com
      • Protocol: https
    • View Result Tree Http2

Running the test shows the following sampler result in the view result tree:

Thread Name:Thread Group 1-1
Sample Start:1970-01-01 01:00:00 CET
Load time:0
Connect Time:0
Latency:0

Data type ("text"|"bin"|""):text
Response code:Non HTTP response code: java.util.concurrent.ExecutionException
Response message:Non HTTP response message: org.eclipse.jetty.io.RuntimeIOException: javax.net.ssl.SSLHandshakeException: nullSession


HTTP2SampleResult fields:
ContentType: 
DataEncoding: null

And the log:

My Setup:

I am using JMeter 5.2.1 with OpenJDK 8 (openjdk version "1.8.0_252") on Linux (version 5.6.15-arch1-1)

(Got the same results with JMeter 5.3 on Ubuntu 20.04, running in CLI mode)

I added the following line at the top of my jmeter startup script, as per requirement of the HTTP/2 plugin:

JVM_ARGS="-Xbootclasspath/p:/opt/jmeter/lib/alpn-boot-8.1.13.v20181017.jar"

How can I solve or debug this issue?

Update:

I found out that as soon as I use alpn-boot as mentioned above, I have the same behavior for regular HTTP requests, so it seems to be a problem from that library. There is a mapping table for jetty-alpn versions against Java versions at https://github.com/jetty-project/jetty-alpn/blob/master/docs/version_mapping.properties and it currently does not contain my Java version.

The docs say

The table only shows the mapping up to OpenJDK 8u242, the last version that required the ALPN boot jar.

But if I start JMeter without the alpn argument, I see results like this (HTTP/2 with HTTPS):

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

回答1:


As I found out, the combination of OpenJDK 8u252 and Jetty 9.4.26 (shipped with JMeter) is not compatible.

The ALPN APIs have been backported to Java 8u252 and Jetty 9.4.28, and alpn-boot is not needed anymore.

More information: https://webtide.com/jetty-alpn-java-8u252/

Updating the Jetty libraries to 9.4.28 helped:

  • Download files from https://repo1.maven.org/maven2/org/eclipse/jetty/jetty-distribution/9.4.28.v20200408/ and https://repo1.maven.org/maven2/org/eclipse/jetty/jetty-client/9.4.28.v20200408/
  • Replace jetty*-9.4.26* files in jmeter/lib by their 9.4.28 counterparts from the downloaded archive

Update: List of files
