   In method 
org.apache.shardingsphere.shardingjdbc.jdbc.core.context.MasterSlaveRuntimeContext.createCachedDatabaseMetaData(Map<String,
 DataSource> dataSourceMap)
   
   
   code is as follows:
   try (Connection connection = 
dataSourceMap.values().iterator().next().getConnection()) {
               return new CachedDatabaseMetaData(connection.getMetaData(), 
dataSourceMap, null);
           }
   
   will this connection be closed?
