Summary

  • track whether a full Bungee/Waterfall proxy runtime actually completed initialization
  • fail initial plugin startup instead of logging a normal loaded/enabled state after an aborted load
  • emit an explicit SEVERE warning that incoming votes are not being processed
  • clear the operational flag once the old runtime is no longer a safe fallback
  • cover the failed-initialization state with a focused lifecycle regression test

Bug

A throwable from VotingPluginProxy.load(...) is currently caught inside reloadPlugin(true). Initial onEnable() then continues and logs VotingPlugin loaded even though the Votifier listener was never initialized. VotifierPlus can continue receiving records while VotingPlugin silently drops them.

Behavior after this PR

On first startup, an aborted full runtime load leaves the runtime non-operational. onEnable() logs:

VotingPlugin proxy runtime failed to initialize; votes are NOT being processed.

and throws instead of advertising a successful load.

For full runtime replacement, the operational flag is cleared only after the previous runtime is no longer a safe fallback. Failures before teardown can therefore leave the existing runtime marked operational.

Compatibility

No configuration, protocol, cache, or database format changes.

This PR is intentionally independent from the reward-journal/HTTP-retention fix so the generic lifecycle safety issue can be reviewed separately.

Validation

Added focused initialization-state coverage. Full CI/package validation should run on this PR.

Summary by CodeRabbit

  • Bug Fixes
    • The plugin now accurately reflects when its proxy runtime is unavailable after startup or during a reload, and when it becomes available again after a successful reload.
    • Logs now indicate when votes are not being processed because MySQL initialization or proxy-state loading has failed.

📝 Walkthrough

Walkthrough

The Bungee plugin now tracks whether its runtime is operational. Startup checks this state after initialization. Reload and shutdown update it, and reload failures log that incoming votes are not being processed.

Bungee runtime initialization

Runtime state and initialization checks
VotingPlugin/src/main/java/com/bencodez/votingplugin/proxy/bungee/VotingPluginBungee.java, VotingPlugin/src/test/java/com/bencodez/votingplugin/proxy/bungee/VotingPluginBungeeInitializationTest.java
The plugin tracks and exposes its runtime operational state. Full reload marks the runtime non-operational before replacement and operational after successful initialization. Startup throws if the first initialization leaves it non-operational. Shutdown clears the state. Reload failures log that incoming votes are not being processed. The test checks the non-operational result when the initial reload does not initialize the runtime.

P1 Badge Propagate Votifier listener registration failure

When Votifier is present and enabled but VoteEventBungee construction or registerListener throws, initVotifierListenerIfNeeded() catches the exception and merely disables the runtime's Votifier flag; this unconditional assignment then lets onEnable() report a successful operational runtime despite having no vote listener. In that compatibility or registration-failure scenario, VotifierPlus can continue receiving votes that VotingPlugin never processes, so listener initialization must report failure before the runtime is marked operational.

Exercise onEnable() in the fail-closed startup test.

The added test calls initializeFirstRuntime() directly after stubbing reloadPlugin(true). It does not call VotingPluginBungee.onEnable(), which contains the runtimeOperational check and the IllegalStateException. No test source invokes this Bungee onEnable() path. Removing the check would therefore leave the added test and existing Bungee tests passing while the fail-closed startup contract is untested.

Add a test that reaches onEnable() with the first reload non-operational and asserts the startup exception.

Set runtimeOperational before releasing reloadLock.

A concurrent onDisable() or second reload can acquire reloadLock after the full reload releases it and before line 511. That operation sets runtimeOperational to false, but the first reload then sets it to true after queue draining and listener initialization. The flag can therefore report an operational runtime after shutdown or a failed concurrent reload.

Set the flag inside the lock after schedulePlatformTasks() succeeds. Keep listener initialization inside the lock if listener readiness is part of the operational contract.

Superseded by #1668, which combines the retained-HTTP recovery fix with Bungee/Waterfall + Velocity fail-closed runtime/listener handling.
