Hi If I run *JFR.check* in build 9+181 , the response indicates that I can invoke *VM.unlock_commercial_features*. This command is not available in the given VM.
The output should not refer to this command i VM where it is not available. Cheers Martin Skarsaune Example: Martins-MacBook-Pro-2:Downloads marska$ java -version java version "9" Java(TM) SE Runtime Environment (build 9+181) Java HotSpot(TM) 64-Bit Server VM (build 9+181, mixed mode) Martins-MacBook-Pro-2:Downloads marska$ /Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home/bin/jcmd 11700 JFR.check 11700: Java Flight Recorder not enabled. Use VM.unlock_commercial_features to enable.
