Jmeter : java.lang.IllegalArgumentException: Dimensions (width=27118 height=6346092) are too large. at dummy sampler

I have dummy sampler where added json response of size 220 kb ,

seeing this error whenever clicking on this dummy sampler

current Xss =1.5G ,Xmx=2.5G

Answer

The reason is that your window dimensions (height and width) are 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");
    }

you have 27118 * 6346092 which gives 172093322856 which is a little bit larger than 32-bit integer maximum value

The question why JMeter tries to display that large window is something I cannot answer without seeing full jmeter.log file preferably with debug logging enabled, it may be somehow connected with LAF/MacOS, you could try something like choosing another LAF from “Options -> Look and Feel” menu:

or if you cannot access it as well you can use [-J command-line argument]6 like:

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