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?

Ask Java: what are some JFR-based tools that you enjoy?

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.
What are some alternatives?
jmx_exporter - A process for exposing JMX Beans via HTTP for Prometheus consumption
hibernate-jfr - a Hiberante listener that generates JFR events
junit-jfr - a JUnit 5 extension that generates JFR events
hypersistence-optimizer - Hypersistence Optimizer allows you to get the most out of JPA and Hibernate. By scanning your application configuration and mappings, Hypersistence Optimizer can tell you what changes you need to do to speed up your data access layer.
