I don't deny that. I even know that it is unwise. But your claim that you can't run JMeter with -Xmx1024M on a system with only 1 GB of memory is technically false: it will run, badly probably, but it will run!
So from that aspect, you won't be able to tell that it is a bad decision to assign that much memory on such a low spec machine. You will only (hopefully!) notice it from erratic results when running a loadtest. Only knowledge of how virtual memory, Java etc works will allow you to make an educated decision on sizing the memory parameters.
