Jmeter：java.lang.IllegalArgumentException：尺寸（宽度=27118 高度=6346092）太大。在虚拟采样器

Question

我有虚拟采样器，其中添加了 json 大小为 220 kb 的响应，

每当点击这个虚拟采样器时都会看到这个错误

当前Xss =1.5G ,Xmx=2.5G

Answer 1

原因是您的 window 尺寸（高度和宽度）是 somehow too large

public SampleModel(int dataType, int w, int h, int numBands)
{
    long size = (long)w * h;
    if (w <= 0 || h <= 0) {
        throw new IllegalArgumentException("Width ("+w+") and height ("+
                                           h+") must be > 0");
    }
    if (size >= Integer.MAX_VALUE) {
        throw new IllegalArgumentException("Dimensions (width="+w+
                                           " height="+h+") are too large");
    }

你有 27118 * 6346092 得到 172093322856 比 32-bit integer maximum value

大一点

为什么 JMeter 试图显示这么大的 window 的问题是我无法在没有看到完整 jmeter.log file preferably with debug logging enabled 的情况下回答的问题，它可能与 LAF/MacOS 有某种联系，你可以尝试类似的东西从“选项 -> 外观”菜单中选择另一个 LAF：

或者如果您也无法访问它，您可以使用 [-J 命令行参数]6，例如：

jmeter -Jjmeter.laf=CrossPlatform -t /path/to/your/test.jmx
