Description

Steps to reproduce:

  1. Open JFR snapshot from dev. build of JDK 21 (jfr-1685451518486.jfr.gz)
  2. There is warning in the messages.log:
WARNING [org.openjdk.jmc.flightrecorder.internal.parser.v1.ValueReaders$ReflectiveReader]: Could not find field with name 'virtual' in reader for 'thread'

This is likely caused by JFR support of Virtual Threads JEP 444.
