      A DESCRIPTION OF THE PROBLEM :
      Trying to print "jdk.SocketRead" (es.onEvent(event, System.out::println);) but it fails on construction of stacktrace:

      java.lang.ClassCastException: class jdk.jfr.consumer.RecordedObject cannot be cast to class jdk.jfr.consumer.RecordedMethod (jdk.jfr.consumer.RecordedObject and jdk.jfr.consumer.RecordedMethod are in module jdk.jfr of loader 'bootstrap')

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      clone: https://github.com/petrbouda/jfr-sockets
      run: pbouda.jfr.sockets.simple.Start
      watch console output

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      JFR Socket jdk.SocketRead event printed
      ACTUAL -
      java.lang.ClassCastException: class jdk.jfr.consumer.RecordedObject cannot be cast to class jdk.jfr.consumer.RecordedMethod (jdk.jfr.consumer.RecordedObject and jdk.jfr.consumer.RecordedMethod are in module jdk.jfr of loader 'bootstrap')
