Question: Usage of OpenJDK instead of Amazon Corretto

[samuelstein]

I saw that the performance tests were made with Amazon Corretto JDK. Their JDK differs from the offical OpenJDK and can include performance optimizations.
Thats why it would be interesting to run the benchmark with OpenJDK and to compare the results with Amazon Corretto.

I don't want to test with more than one JDK as I want to keep the reports simple.
My preference is to test with OpenJDK, but this got replaced with Corretto during some JDK upgrade (11 or 17, I don't recall) because the AMIs don't provide OpenJDK out of the box.

Contributions are welcomed so feel free to send a PR that updates the ami provisioning to use the OpenJdk :)
