Luke Cwik commented on BEAM-14144:
----------------------------------
Of interest in that article was also the jdk-jfr-compat library that allowed us
to compile against the API but I couldn't find a released version of it but
maybe someone else has done the same thing already or we could also implement
stub APIs to compile against since the JDK will provide it's implementation on
the classpath earlier.

> It'd be useful for debugging GC issues in jobs to have allocation profiles
> when it was occurring. In java 9+, JFR is included in the JDK, we could use
> that to record profiles when GC thrashing is detected.
