test jmeter project test_http2.zip Jmeter 5.5, Java 11+

Passing protocol via variable e.g ${PROTOCOL} is causing infinite loop of redirects and java.lang.StackOverflowError

Thank you @antonkislinskiy Thanks for providing an example test as well.

We will be solving it in a future version.

Hi @antonkislinskiy

New version with fixes released. You can access it from the Releases section on GitHub. https://github.com/Blazemeter/jmeter-http2-plugin/releases/tag/v2.0.5
