Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Experimenting with GC-less (heap-less) Java
I haven't had chance to use it properly yet, but I think JfrUnit[0][1] is a good option here to test non-functional behaviour like memory usage and garbage collection.

- Is there a way to write tests to validate the Hibernate-generated queries?
- JfrUnit – A JUnit extension for asserting JDK Flight Recorder events
- Possible to detect performance and memory issues with testing?

Inducing sustained GC
I do not know of any library that would particularly help here, except maybe this thingie might help with writing tests to assert your expected behaviour holds: https://github.com/gunnarmorling/jfrunit (A potentially relevant example here: https://twitter.com/gunnarmorling/status/1335326054496555008). However, there's no public release as of yet.

micrometer-jfr a meter registry that generates JFR events for corresponding Micrometer metrics
What are some alternatives?
hibernate-jfr - a Hiberante listener that generates JFR events
jmfrx - A bridge for capturing JMX data with JDK Flight Recorder
junit-jfr - a JUnit 5 extension that generates JFR events
JavaFlames - One file java script for visualizing JDK flight recorder execution logs as flamegraphs without any dependencies except Java and a browser.
