BreakMe
by JFronny
BreakMe is a Fabric cursed mod that deliberately crashes Minecraft or the host PC, and its name describes that purpose plainly.
What it does
Each feature in BreakMe triggers a failure on purpose. One triggers a fork bomb, which launches a process that keeps multiplying until the system runs out of resources. Another uses JNI calls to open blue-screen windows, and another causes an out-of-memory exception. A further one ends the process with a broken exit code, so the game keeps displaying a window after the player has asked to quit. The mod targets Windows and a Java process, and the damage reaches past the game itself.
The mod works on a client or on a server, and either side can run it while neither needs it. It requires LibJF, which the author's own library supplies, and Mod Menu is an optional companion for the settings screen. Files are published for Fabric across 36 release versions, 1.16.4 – 26.3, and the code is open source under the MIT License.
Key features
Process fork bomb
Launches a self-multiplying process that keeps spawning copies until the machine stops responding.
Windows API crash
Uses unsafe WinAPI calls through JNI to make blue-screen windows appear on Windows machines.
Out-of-memory failure
Forces an out-of-memory exception in the running Java process, ending the session in a crash.
Broken exit code
Leaves the game window on screen after quitting the world, since the shutdown path no longer completes.

Use cases
Testing crash handling
Developers can trigger a known failure to check how a launcher or crash reporter responds to a hard fault.
Who it’s for: The mod suits people who want to test crash behavior or who enjoy cursed mods. Because the failures reach the operating system, it is not meant for ordinary play.

What the author says
BreakMe allows configuring an event (death/taking damage) that causes minecraft to crash. It can also be configured to shut down or crash the whole OS. It uses Fabric (although porting should be trivial, most of the code is standard java & some JNI) Please note that shutting down (or worse: crashing) an OS while…
