I am a member of the Java success team at Oracle, and a senior application architect. I've been a JMeter user and advocate for a long time.
As a programmer, the benefits of going to Java 17 are obvious, I hope. Code is easier to write, easier to read, and more efficient. The Java 8 Enterprise Performance Pack provides Java 17 performance to Java 8 users, but is only available to Java subscribers, who support the continued maintenance of Java 8 and other past-end-of-public-releases versions. The long term support versions of Java are 8, 11, 17, and now 21. Java 11 public support ended in September 2023. Public support for Java 17 ends in September of 2026. I would strongly recommend that JMeter move to Java 17 or Java 21 immediately. Furthermore, the new lightweight threads available in Java 21 would be a huge performance boost to JMeter, so I strongly recommend that JMeter move to Java 21 as soon as practical after moving to Java 11. Running JMeter in a different VM from the application under test should be no burden to users, and the reduced cost in building a test environment due to improved thread efficiency should well offset the increased effort in adding a VM specifically for running JMeter. I further suggest that, if bandwidth allows, that the team consider testing JMeter on GraalVM, which has significant performance benefits over other VMs. Getting JMeter to run in compiled form might also offer certain benefits in terms of startup performance and repeatability (but we'd have to test that).
