>> Correct - this type of event period (beginChunk) will fire once when the JFR recording is begun. It should capture Security Properties (if java.security.Security is loaded) for any recording, no matter when it might begin or end. Similar to how InitialSystemProperty is captured (but that's implemented at native/VM level)

As per yesterday's stack trace, JFR triggers loading of the Security class - so your scenario won't arise with current state. We could include the new Event with period of `endChunk `instead of `beingChunk `setting. That should ensure the properties are only captured when the JFR recording is exiting. 
@egahlin - would you have a preference on this ?
