During a normal full reload, reloadPlugin(true) sets runtimeOperational to false after tearing down the predecessor and does not restore it until MySQL/cache/runtime reconstruction finishes, so any Votifier event arriving in that potentially long window hits this return and is permanently discarded even when the reload succeeds. Velocity has the same sequence. Queue or retry events while a reload is in progress, reserving rejection for a terminal failed state.

On a successful Bungee full reload, reloading is cleared at line 503 before queued messages are drained, the listener is checked, and runtimeOperational is set here. An existing Votifier listener can execute during that interval, observe both flags as false, and permanently discard the vote in RetryingVote.run(). Fresh evidence beyond the earlier review comment is this remaining Bungee-only transition gap; Velocity correctly publishes runtimeOperational before clearing reloading. Move the successful reloading = false transition after this readiness publication, including a terminal transition on listener failure.

There was a problem hiding this comment.
When a pending listener vote is handed off during full reload, shutdown, or queue overflow, this inserts it into the timed-vote cache and the caller immediately removes it from pendingIncomingVotes. Nothing schedules processQueue() after replacement/startup; its normal lifecycle caller is onTimeChangedFinished(), which returns before processing when GlobalData is disabled. On an otherwise healthy GlobalData-disabled proxy, the accepted vote can therefore remain indefinitely in storage instead of being delivered. Schedule a replay after loading or completing this handoff.

There was a problem hiding this comment.
During a full reload, reloadPlugin(true) holds reloadLock across Control shutdown, MySQL initialization, and cache/runtime loading, so a Votifier callback arriving here blocks before the thread-safe pending queue can own the vote. If replacement then aborts, the callback resumes with reloading == false and runtimeOperational == false and rejects that newly arrived vote; Velocity has the same structure. Fresh evidence beyond the earlier reload-window comment is that this revision moved admission itself behind the long-held lifecycle lock, so admission should occur without waiting for replacement completion.

Admit votes before acquiring reloadLock when a reload is active.
Both reload methods hold reloadLock while reloading is true. acceptIncomingVote acquires that lock before it checks reloading, so a vote that waits for the lock cannot use the !reloading exception.
If a replacement fails and leaves runtimeOperational == false, the waiting vote is rejected instead of being added to pendingIncomingVotes. This loses the vote before shutdown persistence can retain it.
Add the reload fast path before synchronized (reloadLock) in both implementations. Keep the capacity-overflow handling under the lock. Do not trigger an additional wakeup while the reload owns the lock; the reload exit paths already call retryPendingIncomingVotes().
🐛 Proposed fix
public void acceptIncomingVote(String player, String service) {

There was a problem hiding this comment.
If a full reload fails before creating its vote cache (for example, MySQL initialization fails), the existing Votifier listener remains registered and newly received votes stay in pendingIncomingVotes because the failed runtime cannot retain them. After the administrator fixes the configuration, every subsequent full reload reaches this check against the same cache-less runtime and returns before creating the healthy replacement, leaving restart—which loses the in-memory votes—as the only recovery path. Continue replacement while carrying these pending votes forward when the predecessor has no usable store; Velocity has the same sequence.

During shutdown, if retainIncomingVoteForRestart returns false—such as when both SQL and the emergency JSON journal are unavailable—this return value is ignored, so the vote remains only in the process-local queue while the runtime and timer are immediately stopped. The accepted vote is then lost when the plugin/JVM exits; shutdown needs a bounded durable fallback or must otherwise handle the failed handoff instead of proceeding as though it succeeded. Velocity's shutdown path has the same issue.

When a Votifier service identifier is 101–2048 characters long, ServiceSiteValidator accepts it and the emergency writer stores it unchanged, but this reader rejects it at 100 characters. If such a vote is journaled while the normal cache/runtime is unavailable, every subsequent recoverEmergencyIncomingVotes fails, the replacement runtime is retired, and all journaled votes remain stranded until the file is manually repaired; validate before journaling or use the full supported service-site bound here.

When a raw Votifier vote is admitted during reload or shutdown before vote() validates it, these fields are serialized unchanged. An invalid or oversized service, a player longer than 100 characters, or a null value can therefore be written successfully, but load() subsequently rejects or throws while reading that same record, causing recoverEmergencyIncomingVotes() to abort every startup until an administrator manually repairs the journal. Apply the reader's validation and bounds before publishing the file, or reject malformed votes before admission.

If persistPendingIncomingVotes() moves accepted votes into the timed cache and ProxyRuntimeReplacementLifecycle.prepare() then fails, the abort path invokes this helper after restoring the old runtime, but the helper only retries the now-empty in-memory queue. With GlobalData disabled, nothing subsequently calls processQueue(), so those durable votes remain stranded until another successful reload or restart. Fresh evidence beyond the earlier replay finding is that the final Bungee helper now calls scheduleQueuedVoteReplay(), while this Velocity helper still omits it.

When all 12 live attempts and the immediate durable handoff fail during a temporary database/JSON outage, this branch leaves the vote in pendingIncomingVotes but schedules no future wakeup. If no later vote or lifecycle action calls retryPendingIncomingVotes(), restoring storage alone never resumes this accepted vote; schedule a bounded backoff retry while retaining ownership.

If the emergency journal contains malformed JSON, JsonParser.parseString throws an unchecked JsonSyntaxException rather than the declared IOException. During Velocity reload or shutdown, persistPendingIncomingVotes() catches only IOException, so when normal vote-cache retention also fails this exception escapes with reload fenced and tasks canceled instead of safely aborting the handoff; wrap parser/schema runtime failures as IOException.

When both the normal cache handoff and emergency-journal write fail, this branch merely returns from onDisable; Bungee cannot cancel plugin or JVM shutdown by returning from the callback, so the process still exits with the accepted votes only in memory. Fresh evidence beyond the earlier finding is that the new boolean check handles the failure solely with this early return, without establishing another durable fallback or preventing shutdown. The Velocity shutdown handler has the same behavior.

Summary
Fix the proxy restart/data-loss failure comprehensively across shared transport retention, Bungee/Waterfall, and Velocity.
This supersedes #1666 and #1667 and incorporates the useful general-purpose parts of the EcoCityCraft fork fixes (notably
656b910and479307e) without importing fork-specific behavior blindly.Retained HTTP recovery
http/outgoing-v1deliveries must remain parked because HTTP cannot safely be reconstructedPLUGINMESSAGING, fall back safely to plugin messaging and restore its encryption handlerProxy runtime safety
Original failure
A PLUGINMESSAGING proxy with
SendVotesToAllServers: trueaccumulated reward-journal IDs inHttpDeliveryIds. On restart those IDs were treated as HTTP work, overriding the configured method. HTTP then failed because it had never been configured, full proxy loading aborted before Votifier listener registration, and the plugin still appeared enabled while later votes were silently lost.Compatibility

Attribution
The retained-listener/fallback direction was validated independently in the EcoCityCraft/ECCVotingPlugin fork. This PR adapts that approach for upstream and adds the broader lifecycle/Velocity protections needed by VotingPlugin itself.
