i was testing JFR with custom events using a mostly empty custom.jfc
file and noticed a large amount of jdk.CheckPoint events in the
resulting repository and dump files (both count and size wise) after a
few hours of uptime (using JDK 14). I tried to explicitly disable the
event in the profile config but it didn't help. It seems to be around
8MB of jdk.CheckPoint events per day for a mostly idling app server.
Accessing the event with the jfr commandline tool or API didn't work
either and I couldn't find any other information on it.
What is it for? Some implementation detail needed for the file structure?
