java.lang.NullPointerException : Inflater has been closed On InputStreamReader 异常

Question

我有以下问题:

当我从项目加载资源时一切正常，但是当我将它放在 .jar 上并尝试加载时出现异常。

代码是:

InputStreamReader reader =
    new InputStreamReader(
        this.getClass().getResource(fileName).openStream())  
CsvReader stream = new CsvReader(reader);  
try {  
    while (stream.readRecord()) {  
        line = stream.getRawRecord();  
        //DO SOMETHING...  
    }  
}catch (Exception e) {  
    System.err.println(e.getMessage());  
    e.printStackTrace();  
} finally {  
    stream.close();  
}

stackTrace 是:

    Inflater has been closed java.lang.NullPointerException: Inflater has been closed

问题发生在 stream.getRawRecord() 上。我还尝试使用 BufferedReader 在 readLine();

上获得相同的结果

有什么想法吗？

这可能是 Java 中的错误。我有一个类似的问题，在这里描述:https://issues.apache.org/jira/browse/FELIX-1032

您的应用程序是否使用某些特殊的类加载器设置运行？
