Description
If you specify a settings file wth less than 4 characters, the JVM prints the following error message at start up: begin 0, end -2, length 2 Error occurred during initialization of VM Failure when starting JFR on_vm_start This is not very helpful. Note, JFR accepts names without file extension, for example "default" and "profile". it should also be possible to start without a file as this is a convenient way to turn off the default events.Perhaps $ java -XX:StartFlightRecording:settings=none
