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

[Langer, Christoph]

Hi Denghui,

this is quite a large JFR enhancement.

Looking at the 11u webrev, I didn't see any obvious issues although there are obviously quite some alterations from the original patch. I'll run it through our regression testing.

However, in any case, we need to carefully decide if and when we allow this patch to jdk11u-dev. I'll get back to you soon.

Best regards
Christoph
