[MC-129374] Crash on 32 bit JVMs: "Unable to bootstrap datafixers" due to stack overflow

Workaround for clients < 1.13-pre2

Increase the stack to 1 MB
- In the Edit Profile menu in the Launcher, check the JVM Arguments box, and add -Xss1M

Solution for servers

Increase the stack to 1 MB
- Add -Xss1M to the server startup script

Possible cause

On 32 bit JVMs the default stack size is 320k whereas on 64 bit JVMs the default stack size is 1M
