Apache Commons FTPSClient上传无法完成

如何解决Apache Commons FTPSClient上传无法完成

我正在使用commons-net 3.7和OpenJDK11。FTP服务器是TLSv1.2隐式的。 我可以检索文件，但是当我尝试存储文件时，它会挂起。当我检查storeFile的socket.close();方法调用时，等待输入。

我尝试将InputStream复制到OutputStream的方式。当我尝试关闭OutputStream时，也会发生同样的事情。等待，并发生相同的错误。

为什么无法关闭套接字并结束存储文件？谢谢。

        FTPSClient ftpsClient = new FTPSClient(true);
        ftpsClient.connect("host",990);
        ftpsClient.enterLocalPassiveMode();
        ftpsClient.setFileType(FTP.BINARY_FILE_TYPE);
        ftpsClient.setControlKeepAliveTimeout(300);
        ftpsClient.setBufferSize(1024000);
        ftpsClient.login("user","password");
        // login is successful,everything seems fine
    
        InputStream inputstream = new FileInputStream("test.pdf");
        ftpsClient.storeFile("/upload",inputstream); 
        // waits 4-5 minutes and gets connection reset
        // I can retrieve and delete files,only uploading is problem.
