     - Unsafe_Universal_Forkbomb: Launch a self-multiplying process
     - Unsafe_Windows_WinAPI: Do some JNI-magic to instantly produce a blue-screen on windows
+    - Unsafe_Universal_OOM: Causes an OOM exception
     - Broken_Universal_ExitCode: Exit the integrated Server. The game still displays, but you can no longer interact with the world or quit.
+    - Safe_Universal_Hang: Hang both the client and integrated server thread.
     - Safe_Universal_Exception: Performs an invalid operation. Behaves like every other crash and just closes the game, leaving a crash log.
     - SemiUnsafe_Universal_Exception: Throws a security exceptions. This does not work properly for 1.16.2
     - SemiUnsafe_Universal_Shutdown: Attempts to run a shutdown command. Since these are specific to some systems this might not always work.
+    - SemiUnsafe_Universal_Segfault: Causes a segmentation fault using lwjgl.
