If the jfr file is created by JDK 8 or JDK 11, and use jfr view to show the active-settings view, the result is invalid, missing many settings.

The reason is the endTime of jdk.ActiveSetting on JDK 8 or JDK 11 increases naturally, the time between two consecutive events is approximately a few microseconds, but the query statement of active-settings view used LAST_BATCH(), It assumes that the end time of events are the same. For JDK 17 and above, this assumption is correct, but not for JDK 8 and JDK 11.
