我是Infinispan的新手，并且一直在玩它。我认为我发现了一个错误。如果缓存为 empty ，并且我们有两个正在运行的节点（并且这些节点实际上必须位于单独的虚拟机上-它不能只是2个jvm进程），然后是node＃上的第二个进程1执行以下并行流操作：
using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.IO; //For MemoryStream
using System.Web.Services; //For WebMethod attribute
using Bytescout.BarCode;

using System.Drawing;
using System.Drawing.Imaging;
using System.Threading;

{
}
// int i = 0;
protected void Scan_Click(object sender, EventArgs e)
{
Rectangle rect = new Rectangle(0, 0, 2000, 1000);
string filePath = AppDomain.CurrentDomain.BaseDirectory;
string filePath2;
filePath2 = @"" + filePath + "\\images\\qr code stuff\\fileName.png";
//do stuff
using (Bitmap bmp = new Bitmap(rect.Width, rect.Height, PixelFormat.Format32bppArgb))
{
using (Graphics g = Graphics.FromImage(bmp))
{
g.CopyFromScreen(rect.Left, rect.Top, 0, 0, bmp.Size, CopyPixelOperation.SourceCopy);
}
if (System.IO.Directory.Exists(filePath2) == true)
{
bmp.Save(filePath2, ImageFormat.Png);
bmp.Dispose();
}
else
{
File.Delete(filePath2);
bmp.Save(filePath2, ImageFormat.Png);
bmp.Dispose();
}
try
{
IBarcodeReader barcodeReader = new BarcodeReader();
var barcodeBitmap = (Bitmap)Bitmap.FromFile(filePath2);
var barcodeResult = barcodeReader.Decode(barcodeBitmap);
Output.Text = barcodeResult.Text;
Output.NavigateUrl = barcodeResult.Text;
}
catch
{
Output.Text = "No barcode found";
}
}
}
}
}
您将收到以下错误（主要错误是我认为“无效的lambda反序列化”）。注意：如果缓存中填充了一些数据，则不会发生此错误。我试图（合理地努力）跟踪代码，但无法找出问题，尽管我怀疑这与反序列化某种空的收集器有关。...有人看到过或认为这很可能错误（相对于用户错误？在发布之前，我尝试了很多事情...。）。任何解决方法？ （或者在实际的相关代码中可能是超级简单的“真实”修复程序？）
final List<String> max = c

此外，尽管我认为这无关紧要，但这是缓存的定义：
