---------------------------------

Did you try the -a option? (https://solr.apache.org/guide/solr/latest/deployment-guide/solr-control-script-reference.html#start-parameters)

> I want to be able to start solr with JFR and provide the JFR args through the CLI.
> Those java parameters are of the form -XX:FlightRecorderOptions=stackdepth=128.
>  
> However when I provide those parameters, I get the following error message:
> {{ERROR: -XX:FlightRecorderOptions=stackdepth=128 is not supported by this script}}
>  
> {{}}
> This is due to the check in solr [script|https://github.com/apache/solr/blob/main/solr/bin/solr#L1793]: 
> {{    if [ -z "${1:-}" ]; then}}
> {{      break # out-of-args, stop looping}}
> {{    elif [ "${1:0:2}" == "-D" ]; then}}
> {{      # pass thru any opts that begin with -D (java system props)}}
> {{      SOLR_OPTS+=("$1")}}
> {{      PASS_TO_RUN_EXAMPLE+=("$1")}}
> {{      shift}}
> {{    else}}
> {{      print_usage "$SCRIPT_CMD" "$1 is not supported by this script"}}
> {{      exit 1}}
> {{    fi}}
>  
> The line
> {{elif [ "${1:0:2}" == "-D" ]; then}}
> should be replaced by 
> {{elif [ "${1:0:2}" == "-D" -o "${1:0:3}" == "-XX" ]; then}}
