Review comment (suggestion):
same as above: 


```suggestion
        Map<String, Object> props = createValidConfigProps(Collections.emptyMap(), Collections.emptyMap(), Collections.emptyMap());
```

Code after:
        config.put(SslConfigs.SSL_KEYSTORE_KEY_CONFIG, "keystoreKey");
        config.put(SslConfigs.SSL_KEYSTORE_CERTIFICATE_CHAIN_CONFIG, "keystoreCertificate");
        config.put(SslConfigs.SSL_TRUSTSTORE_CERTIFICATES_CONFIG, "truststoreCertificate");
        config.put(SslConfigs.SSL_TRUSTSTORE_PASSWORD_CONFIG, "truststorePassword");
        config.put(SaslConfigs.SASL_JAAS_CONFIG, "saslJaas");
    }

    private void assertMaskedSensitiveConfigurations(String configString) {
        String[] sensitiveConfigKeys = {
            SslConfigs.SSL_KEYSTORE_PASSWORD_CONFIG,
