I and Amazon also would love to see JFR backported and are willing to contribute to the effort.

However, a lot of Java applications are still running on JDK 8. Thus we back-ported JFR from 11 to 8 on x86-64 platform, which actually has been widely used at Alibaba. We believe it is stable enough to be contributed back to the community. By contributing our patch, the community can help make it work on other platforms too. So, I’d like to file a JEP and propose contributing it to OpenJDK8project, then people can work together to make the patch be pushed finally. What do you think?

This is awesome, I've been toying with this idea myself lately, so I'm
very happy you would like to contribute this code, I would support
this proposal completely, and I'm very curious to see the actual
I think you are right in filing a JEP, it's the right approach for such changes.
On to some specific, Flight Recorder comes with some java API for user
code event generation, did you also backport that?
