   We (me and @gripson) found  a bug in jdbc-connector. when creating DruidDataSource
   
   in `DBUtils.java`
   
   ```
   
           Map<String, String> map = new HashMap<>();
           map.put("driverClassName", "com.mysql.cj.jdbc.Driver");
           map.put("url",
                   "jdbc:mysql://" + config.getDbUrl() + ":" + config.getDbPort()  + "?useSSL=false&verifyServerCertificate=false&serverTimezone=GMT%2B8&characterEncoding=utf8");
           map.put("username", config.getDbUsername());
           map.put("password", config.getDbPassword());
           map.put("initialSize", "1");
           map.put("maxActive", "2");
           map.put("maxWait", "60000");
           map.put("timeBetweenEvictionRunsMillis", "60000");
           map.put("minEvictableIdleTimeMillis", "300000");
           map.put("validationQuery", "SELECT 1");
           map.put("testWhileIdle", "true");
           log.info("{} config read successful", map);
           DataSource dataSource = DruidDataSourceFactory.createDataSource(map);
           log.info("created data source");
   
   ...
   ```
   
   Here the datasource creation could fail. We are trying to find out why createDataSource would fail.
   
   My source connector configuration:
   ```
   {
       "connector-class":"org.apache.rocketmq.connect.jdbc.connector.JdbcSourceConnector",
       "rocketmqTopic":"jdbcTopic",
       "dbUrl":"127.0.0.1",
       "dbPort":"3306",
       "dbUsername":"root",
       "dbPassword":"root",
       "whiteDataBase": {
           "jdbc":{
              "person": {"NO-FILTER": "10"}
            }
         },
       "mode": "bulk",
       "task-parallelism": 1,
       "source-cluster": "172.17.0.1:10911",
       "source-rocketmq": "localhost:9876",
       "source-record-converter":"org.apache.rocketmq.connect.runtime.converter.JsonConverter"
    }
   
   ```
