Although this question is probably more to do with Java Flight Recorder than Mission Control I could not find a specific JFR space so thought I would try here.
My issue has to do with JFR seemingly logging (finding?) event data that is excessively old and I cannot figure out why. For some reason when I enable JFR I seemingly get events from years ago. I came across this article (https://blogs.oracle.com/poonam/clarifying-some-confusion-around-java-flight-recordings ) and it does make sense that JFR might pick up some events that occur before you actually start recording. But I cannot understand how one can start a JVM with JFR enabled and have events with a timestamp of more than 4 years prior to that JVM being started. All machine's dates are set properly (and I have reproduced this behavior on a server with ntpd running). I have checked for logs in the user's <home directory>/.java. I've also cleared out /var/logs. I've tried installing a fresh version of the JDK and have tried with both JDK 8 and 11. I've also tried loading the JFR recording data in two different Mission Control apps (Oracle and Azul's Zulu).
Here are some screen captures showing the data I see:



Note that the JVM start time listed is correct (today's date) and yet somehow events span 229 weeks and 5 days? If anyone has any ideas let me know because my Googler is very worn out at present...
Thanks!
