Low-Overhead Heap Profiling

[JC Beyler]

Hello all,

This is a follow-up from Jeremy's initial email from last year:
http://mail.openjdk.java.net/pipermail/serviceability-dev/2015-June/017543.html

I've gone ahead and started working on preparing this and Jeremy and I went
down the route of actually writing it up in JEP form:
https://bugs.openjdk.java.net/browse/JDK-8171119

I think original conversation that happened last year in that thread still
holds true:

 - We have a patch at Google that we think others might be interested in
    - It provides a means to understand where the allocation hotspots are
at a very low overhead
    - Since it is at a low overhead, we can leave it on by default

So I come to the mailing list with Jeremy's initial question:
"I thought I would ask if there is any interest / if I should write a JEP /
if I should just forget it."

A year ago, it seemed some thought it was a good idea, is this still true?

Thanks,
Jc
