使用Jets3t在s3上获取存储桶列表时出现异常

Question

使用S3服务我试图从所有桶中检索列表.虽然我这样做我得到一个例外.

我收到S3服务异常:java.lang.Long无法强制转换为java.lang.Integer.

这是代码:

    String awsKey = "awskey";
    String awsSecret = "secret";
    AWSCredentials aws = new AWSCredentials(awsKey,awsSecret);

    //communicate with s3
    try{
    S3Service service = new RestS3Service(aws);

    //get buckets
    S3Bucket[] buckets = service.listAllBuckets();

这是堆栈跟踪:

任何帮助,将不胜感激.谢谢.

这是http客户端的一个问题,不得不使用旧版本.

使用4.3.1,不得不使用4.2.
