When running the following command line:

/usr/bin/java -jar /tmp/swarm-client.3.19.jar \

   -disableSslVerification \

   -deleteExistingClients \

        -disableClientsUniqueId \

        -showHostName \

        -noRetryAfterConnected \

        -executors=7 \

        -labels 'blftest' \

        -master https://myjenkins.example.com \

       -username jenkins \

        -passwordEnvVariable ADMIN_PSW

I received the following output
