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.
