      We have some domains with WebLogic 14c (14.1.1.0.0) on JDK 11. We tried lots of JDK JFR options to fix this error:

      ####<Dec 5, 2022, 4:41:08,372 PM Central European Standard Time> <Warning> <RMI> <qassec01> <KOBAK_CORE01> <[ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)'> <<WLS Kernel>> <> <66c2c0b1-5ae4-4af0-a91e-9397aab80d16-0000000c> <1670254868372> <[severity-value: 16] [rid: 0:8:14:2063] > <BEA-080004> <An error was generated by the RMI server: weblogic.jndi.internal.RootNamingNode.lookup(Ljava.lang.String;Ljava.util.Hashtable;)
       java.lang.NoClassDefFoundError: Lcom/oracle/jrockit/jfr/client/FlightRecorderClient;.
      java.lang.NoClassDefFoundError: Lcom/oracle/jrockit/jfr/client/FlightRecorderClient;
              at weblogic.utils.StackTraceDisabled.unknownMethod()
      >
      

      Our WLSDM command line parameters:

      -javaagent:/share/oracle/wlsdm-beta/wlsdm_agent.jar -Dwlsdm.agent.logLevel=INFO -Dwlsdm.agent.extendedBackendMonitoringEnabled=true -XX:+DisableExplicitGC -XX:FlightRecorderOptions=repository=/ou01/app/WLSDM/qsec14/JFR -XX:+FlightRecorder
      

      I can’t disable FlightRecorder (I tried with -XX:-FlightRecorder). If I want to remove this error I have to remove WLSDM agent from Managed Server.

      Is there any fix for this?

      Thanks:
