How to Fix java.lang.StackOverflowError

Fix java.lang.StackOverflowError in Minecraft by increasing stack size and identifying mods with infinite recursion.

Quick Fix

Add -Xss4m to JVM arguments to increase thread stack size. If caused by a mod, remove it.

Error Message

java.lang.StackOverflowError

How to Fix

1

Add -Xss4m to your JVM arguments

2

Remove recently installed mods or plugins that may cause recursion

3

Check data packs for circular function calls

4

Remove deeply nested command block chains

5

Review server logs for the stack trace to identify the problematic mod

Common Causes

  • Infinite recursion in a mod or plugin
  • Deeply nested command block chains
  • Circular references in data packs
  • Stack size too small for complex mod interactions

Diagnostic Steps

  1. Read the full stack trace to find which mod or class is repeating
  2. Increase stack size with -Xss4m
  3. Disable suspected mods and test
  4. Check data packs for recursive function tags

FAQ

What causes a StackOverflowError?

It happens when a method calls itself endlessly (infinite recursion), filling up the call stack. In Minecraft, this is usually a mod bug.
