Root cause identified and fixed in 12.0.5.

All six crashes share the same cause: a rule's Match regex matches a command (e.g. ^\/(bf|bfly|fly)$ or ^\/(blockfly|bf)$), and the rule's Player Commands then dispatches a command that is itself matched by the same regex. That re-fires the same rule on the player's command preprocess event, which re-dispatches, and so on until the JVM stack is exhausted. Because the recursion is so deep, the actual StackOverflowError surfaces at whatever frame happened to be on top when the stack ran out — that's why each report shows a different "Unknown cause" frame (Platform.toPlayer, Gson.toJson, HashMap.put, log4j, adventure.minimessage, etc.). They are all symptoms of the same loop.

Concretely, with Player Commands: [fly] and Match: ^\/(bf|bfly|fly)$, the rule alias dispatches /fly, which /fly matches itself and re-enters the rule → infinite recursion.

Fix

I've added a per-thread recursion guard to Operator$OperatorCheck.executeOperators. If the same rule is already on the execution stack for the current thread, the nested dispatch is skipped and a clear warning is logged instead of crashing. There is also a hard recursion-depth cap of 20 to break any longer A → B → A cycle. The guard is identity-based per rule, so legitimate rule chains (rule A dispatches a different command handled by rule B) continue to work normally.

What to do in your config (recommended)

Even with the crash fixed, you almost certainly want to avoid the loop entirely. For your alias rule, either:

1. Exclude the dispatched command from the regex, e.g. ^\/(bf|bfly)$ (drop fly so the dispatched /fly isn't re-filtered), or
2. Add ignore string fly / ignore perm essentials.fly.bypass-rules so the rule skips itself when matching /fly directly.

Closing as fixed. Update ChatControl to 12.0.5 when available on BuiltByBit. Thanks for the auto-reports.
