Ioi keeps an excellent set of samples in the repo:
https://github.com/openjdk/leyden/tree/premain/test/hotspot/jtreg/premain
For example, 5-step process mentioned in the slides is illustrated by:
https://github.com/openjdk/leyden/blob/premain/test/hotspot/jtreg/premain/lib/premain-run.sh
https://github.com/openjdk/leyden/blob/premain/test/hotspot/jtreg/premain/spring-petclinic/Makefile
If you have any ideas/requests how to improve those, please, speak up.
Or even contribute :-)
To clarify, currently employed 5-step process is interim. We temporarily
settled on it to simplify prototyping effort. There's active work going
on to migrate to a workflow which requires only a single step, but it's
in its early days of development:
https://github.com/openjdk/leyden/tree/premain/test/hotspot/jtreg/premain/javac_new_workflow
Best regards,
