Hey, I'd like to take on this task if that's okay.

@philwebb We can do some additional documentation in our buildpacks as well to help with this as well.

We can document something on our side but I wonder if that's a good idea. By the time this issue was created, this was already renamed and the references above are outdated.
Looking at https://github.com/paketo-buildpacks/bellsoft-liberica/commit/06551eccf11d9b5f58a7adca0b716482ddf614bc#diff-04c6e90faac2675aa89e2176d2eec7d8 it looks like the property to use now is JAVA_TOOL_OPTIONS.

@nebhale It does feel like some more user-facing Packeto documentation that we could link to would be very useful.
Comment From: nebhale
Yep, first thing on my list either during my downtime this week or just after SpringOne. The entire Paketo team is adding that as we speak.

Paketo buildpacks documentation has been updated, so the Spring Boot docs can now link to the relevant section in paketo.io: https://paketo.io/docs/buildpacks/language-family-buildpacks/java/#runtime-jvm-configuration.
We should include a disclaimer that the information provided by this link only applies when the Paketo builder and buildpacks are used, and other CNB implementations might work differently.
