      Description

        "I've run into a strange issue with JFR recordings on Java 21 when taking multiple JFR recordings.The first recording works as expected. If I do not immediately start the next recording, periodic JFR events are no longer produced. Events based on actions still appear (e.g. virtual thread pinning), but periodic events are missing.I cannot reproduce this issue on Java 17, but it does seem to be 100% reproducible on Java 21 (including a 21.0.1+12 fastdebug build)."

        Impact = High, loss of data
        Likelihood = Low, only happens with JFR in some scenarios
        Workaround = High, no known workaround

        HLH -> P2
