Windows 10: windows 11 pro When JAVA heap expands, system crashes

I have a JAVA app that uses about 16GB VM. When I run a JAVA app with a large heap, windows crashes very quickly. Before it crashes, I can see the app using 8-12GB memory, presumably less when modified pages are moved to swap. I set the system VM to 1024-262144 so it can handle up to 256GB. When I run a gcc program under Linux Launcher to find the max malloc size, it says about 10GB. The JAVA app still crashes the system. I have all the current MS Windows Updates. The system has 16GB ram.Device name THIS-JRKDUTOF4M Processor AMD Ryzen 5 8600G w/ Radeon 760M Graphics 4.35 GHz Inst

windows 11 pro When JAVA heap expands in WSL2 or command line, system crashes

On many cases the RAM is sufficient, so I felt a low starting swap size was not a big deal. It crashes the system the same with the system managed size. If it creates delays when expanding, that is still no cause for crashes. I ran it in a bat file with a double quoted full path to the java.exe, and with output redirected, and the system dies if I run the bat from the windows command line or run the .class from the WSL2 Ubuntu bash command line. I expanded WSL2 max heap but that does not seem to help, either. There seems to be another bug in the WSL2, as setting it to 128GB got me a max malloc of 20GB. I have gone much bigger in real Linux Ubuntu after adding to the swap space.

Like any .exe, Release 22 java.exe should not be able to crash Windows 11.
