This is more of an enhancement than a bug as it changes how -XX:StartFlightRecording and icmd JFR.start work. This is not a low risk fix as it may impact scripts. There is also a very simple workaround, specify the filename manually, i.e -XX:StartFlightRecording:filename=recording.jfr 

If backporting this issue at all, we should wait until we are sure it works as expected in production, which means waiting after JDK 21 has been released.
