I suppose that you use Java 8 and Jetty to provide HTTP/2 impl.
You need to add in the boot classpath the ALPN impl.
java -Xbootclasspath/p:<path_to_alpn_boot_jar>

Hi all,
I am developing a HTTP2 sampler plugin for JMeter. When I run it in JMeter
for testing I get the following error. Can someone help me to solve the
error?
Thank you.
