Executing a run.bat file with the code:
@echo
java -Xmx1024M -Xms1024M -jar server.jar nogui
PAUSE
will result in a alleged stack overflow, i have tested and troubleshooted different -X JVM tags. all i found was that including an -Xss1M tag for thread size stopped the stack overflow, but was not able to carry the load of the server under just 1M.
What I expected to happen was:
The server to run, with minor latency issues, but not with a total failure and stack overflow, after dedicated 1M through -Xss i assumed it'd work to test out, but i cannot run a server on just 1M of allocated thread size.
How can i run the server with the first run.bat i have copied above? what have i done wrong and how can i fix this.
Do not discredit this report as a duplicate, i have seen those and they are not fully helpful to this scenario.
What actually happened was:

Steps to Reproduce:
1. Run the latest server.jar for 1.13pre2 using the same run.bat file as i have, in the same environment too.
2. to see the contrary, test out the bat file with the alternative of adding -Xss1M to the run.bat
Thankyou

⚠️ Please do not mark issues as private, unless your bug report is an exploit or contains information about your username or server.
Xss1M isn't 1M of thread size; it's 1M of stack size. The default is much less than that; increasing it shouldn't break your server.
This is sort-of a duplicate of MC-129374 (/MC-131498), but it's only apparently happening with servers now (when it shouldn't be happening at all). I'm not 100% sure whether to resolve it as a duplicate or not.

Is a duplicate.
You have to add the -Xss argument, not replace all other args:
java -Xmx1024M -Xss1M -jar server.jar@kumasasa, I had done this too. So no help really. The issue has been fixed in the new patch regardless.
