Steve Niemitz commented on BEAM-14144:
--------------------------------------
Oh interesting I didn't realize it was backported to java 8. Sadly dataflow
(v1) uses an extremely old JDK build (1.8.0u151) so it wouldn't work on there.
If others wanted to use it though we could certainly relax the restriction.

> 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.
