RFR: 8303134: JFR: Missing stack trace during chunk rotation stress

Mon Jul 3 18:40:22 UTC 2023

Greetings,

please help review this fix to some problematic situations in JFR where data can be lost. Most problems originate from  writing event data in the wrong epoch due to safepointing. Detailed information about the changes are in the JIRA issue.

Testing: jdk_jfr, stress testing.

Thanks
Markus
