While Apparmor enabled:
Whenever I start the JVM after turning on the JFR through JVM parameter, the JVM crushes with the following error.
# Java VM: Java HotSpot(TM) 64-Bit Server VM (25.181-b25 mixed mode linux-amd64 compressed oops)
# Problematic frame:

My JFR settings are like:
JFR_JAVA_OPTS="-XX:+UnlockCommercialFeatures -XX:+FlightRecorder -XX:FlightRecorderOptions=defaultrecording=true,disk=true,settings=profile,repository=/tmp,maxage=60m,loglevel=info"
When Apparmor is disabled JVM starts without any error.
My requirement is, I have to keep Apparmor enabled for my app. How should I get rid of this error?
Thanks.
