[jdk15u-dev] RFR: 8255992: JFR EventWriter does not use first string from StringPool with id 0

Thu Jun 3 18:37:59 UTC 2021

I'd like to backport JDK-8255992 to 15u as a prerequisite for JDK-8257621 and for parity with 11u.
The patch applies cleanly.
Tested with tier1 and jdk/jfr tests, the only failure is jdk/jfr/api/recording/event/TestReEnableName.java, that will be fixed by follow-up backport of JDK-8257621.
