[11u] RFR 8185525: Add JFR event for DictionarySizes

[Langer, Christoph]

Hi Andrey,

thanks for your comments about these JFR event backports.

Can you compile a list of items that you’d like to backport to both, 8u JFR and 11u? Then we can sync together with Mario and Andrew Haley and take a decision about what we want to approve.

Cheers
Christoph

Hi guys, All,

No, there is not special reasoning for back-porting of this particular event type. Feel free to reject the request. A few comments though
- we at Azul see JFR as a very useful and successful tool for solving customer issues. So in general we try to keep up with new fixes and features there, unless we consider fix as too risky or inappropriate
- all these JFR backports proposed are undergo full test cycle, involving all tests we have (including of course all jtreg) on all platforms supported by Azul (well, a lot)
- @Christoph regarding fix not yet pushed to 8u. We (Marrio and team involved into JFR to 8u backporting)  have a policy that we don't push into 8u until it's pushed into 11u. Hence it's not pushed

Regards,
Andrey
