I've got 3 further comments to shorten the description texts.

I would leave out the word "Various" here

src/hotspot/share/jfr/metadata/metadata.xml line 803:

Same here, drop the "Various"

src/hotspot/share/jfr/metadata/metadata.xml line 812:

Here only say "Information about...", leave out the "Contains"
