我有一个由服务器生成的CSV文件作为报告。CSV文件有超过100k行的文本。我正在Kotlin中使用CsvMapper阅读该文件，但我最终得到了IOException。
下面是我实现的代码：

//Declare the mapper object
private var csvMapper = CsvMapper().registerModule(KotlinModule())
        
//Generate Iterator
inline fun <reified T> getIterator(fileName: String): MappingIterator<T>? {
    csvMapper.disable(JsonParser.Feature.AUTO_CLOSE_SOURCE)
    FileReader(fileName).use { reader ->
        return csvMapper
                       .readerFor(T::class.java)
                       .without(StreamReadFeature.AUTO_CLOSE_SOURCE)
                       .with(CsvSchema.emptySchema().withHeader())
                       .readValues<T>(reader)
    }
}
    
//Read the file using iterator
fun read(csvFile: String) {
    val iterator = getIterator<BbMembershipData>(csvFile)
    if (iterator != null) {
          while (iterator.hasNext()) {
                try {
                     val lineElement = iterator.next()
                     println(lineElement)
                } catch (e: RuntimeJsonMappingException) {
                    println("Iterator Exception: " + e.localizedMessage)
                }
          }
     }
}

打印完第10行代码后，其抛出如下图异常：

Exception in thread "main" java.lang.RuntimeException: Stream closed
    at com.fasterxml.jackson.databind.MappingIterator._handleIOException(MappingIterator.java:420)
    at com.fasterxml.jackson.databind.MappingIterator.next(MappingIterator.java:203)
    at Main$FileProcessor.read(Main.kt:39)
    at Main.main(Main.kt:54)
Caused by: java.io.IOException: Stream closed

如何防止出现“Stream Closed”异常？
