is the same instance as the currently assigned backend. Preserve assignment and
close the previous backend only when the replacement is a different instance.
- Around line 125-129: Coordinate read(), populate(), queueChange(), flush(),
and remove() with lifecycle transitions using a shared lifecycle lock, and make
replaceBackend() and close() acquire its exclusive lock across their full
operations. Ensure normal operations cannot continue after shutdown begins or

after close.

… shutdown Route explicit and scheduled batches through the existing UserDataCache queue and notification hooks with an explicit backend destination. Stop new admission before shutdown, drain admitted work including notifications, retain failed batches, and provide an observed worker-only closeAsync. Cancel redundant timer work without server-thread termination waits. Add nine lifecycle/adapter regressions with memory SQL providers and real cache code. Enable the normal Maven PR job for this stacked base so this head gets actual repository test and packaged-artifact validation. Local JDK21 isolated compilation/execution of the candidate runtime and cache adapter passed replacement, scheduled flush and notification/shutdown barrier checks (external APIs stubbed; Lombok getters expanded only in the isolated copy). Syntax and incremental whitespace checks passed. Full local Maven and live database/server checks remain unavailable. No dependency, shading, FLAT, native loader, or unrelated PR changes.

Register one manager-level initializer so caches created through existing getCache/cacheUser paths or inserted later acquire the selected writer and runtime admission gate before mutation/flush. Preserve existing queues, notifications and legacy virtual cache-loading hooks. Refuse monitor-order inversions and retain failed batches for retry. Publish Bukkit owner lifecycle state atomically without eagerly taking over active legacy batches. Attachment failure leaves the owner reusable and an active legacy batch leaves a reachable runtime with retryable flush/close. Honor allowStorageLookup before populating caches for no-database modes. Add 14 focused headless regressions with the real manager/cache and in-memory providers plus mocked platform boundaries. Local Java 21 syntax and incremental whitespace checks passed; full local Maven and live-server checks remain unavailable. GitHub Actions must validate this candidate.

Keep lifecycle admission independent from blocking SQL checks so cached reads and queued cache mutations remain safe on the primary thread. Require worker context only at actual storage boundaries, including scheduled bound writers. Use the shared/read lifecycle lock for normal operations and exclusive transitions for replacement/shutdown, and stream startup enumeration through the updated SQL backend contract. Includes the concurrent late-cache/atomic-binding fixes already on this branch and restacks them onto the latest shared SQL backend head.

Capture an operation-local cache version before flush/load and merge only newer local mutations when publishing the SQL snapshot. Keep changes that have already left the pending queue, retain refreshed untouched fields, and reject snapshots targeting a replaced cache instance. Later full refreshes/populations win over older loads. No database wait is placed under the cache monitor or memory-only runtime admission path. Preserve concurrent f0fba33 legacy routing and e732e4b's SQL restack; their changes were compared before applying these five verified file blobs. Reuse the existing cache and queue; per-key metadata stores versions, not another copy of user values. Add eight deterministic headless regressions for pending/completed writes, memory-only changes, replacement, load failure, retry, overlapping loads and token identity. Local Java21 syntax parsing and reconstructed incremental whitespace checks passed. Full local Maven/JUnit and live-server/database tests are unavailable; GitHub Actions must validate the complete build and fresh shaded artifact. Follow-up to Codex 4000149174; no dependency, packaging or workflow changes.

Resolve the shared manager null-safely and use the captured instance for this operation. Legacy SQL providers remain usable before UserManager or UserDataManager exists; a bound shared route continues to handle failures through its lifecycle gate instead of silently falling back. Validate the requested storage before either route. Actions on 8eb0984 compiled and ran 452 tests. All eight new population-race regressions passed, but nine existing legacy-storage tests exposed this null-manager regression. Preserve those tests unchanged. Local Java21 syntax and incremental whitespace checks passed; full build requires CI.

There was a problem hiding this comment.
When shared retirement completes exceptionally, such as when a final database write fails, awaitCleanup returns false and this condition skips both the graceful shutdown here and the later shutdownNow. No production path schedules another retirement after onDisable returns, while UserDataManager created this executor with the default non-daemon thread factory, so the thread and its plugin/cache/backend references survive disable or reload indefinitely. Add a bounded retry or recovery path that eventually terminates the executor.

When native enumeration fails partway through, MySQL.forEachUser catches SQL errors and callback exceptions, while UserTable.forEachUser catches SQL errors; both then return normally. Because these calls discard their completion callbacks, enumerateUsers and SharedUserDataRuntime.startupForEach report a partial list/count as success, allowing startup and bulk operations to silently skip users. Route enumeration through an API that propagates failure or extend the completion contract with an error result.

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win
A blank resolved name can overwrite the stored PlayerName. The name write uses AdvancedCoreUser.getPlayerName(), which returns "" when the playerName field is still null and no temp-cache value exists. The caller in UuidLookup previously wrote the live Bukkit name, so the delegation now makes this state reachable while a player is online.

Log the removal throwable, not only its class name.
The failure message tells the operator to check the server log. This call records only the exception class name, so the log has no message, cause chain, or stack trace. Keep the throwable out of sender.sendMessage, but pass it to the server logger. The same pattern exists in startStorageConversion at Line 689.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Use a thread-safe list for the cross-thread event log.
events is a plain ArrayList. The shutdown worker adds entries while the main thread polls events.contains("pre") and later calls events.indexOf(...). Unsynchronized concurrent access to ArrayList can throw during a resize or never publish the added element, which makes this test flaky in CI.
🛠️ Proposed fix
- var events = new ArrayList<String>();

There was a problem hiding this comment.
When a downstream plugin calls the public getInt on Bukkit's primary thread for an uncached user, getCache() installs an empty placeholder and queues population, after which this branch returns the supplied default even when storage contains a different value; getString, getValues, and hasData have the same incomplete-snapshot behavior. This silently changes established return values and can make callers act on false user state, so expose an asynchronous completion or explicitly reject the unavailable fresh read rather than presenting the placeholder as authoritative.

There was a problem hiding this comment.
When Bukkit calls shutdown on its primary thread and a cache flush is still pending, awaitCleanup returns false, this conditional leaves the storage worker alive, but shutdown nevertheless proceeds through afterExecutorGrace() and afterExecutorShutdown() (including the plugin's onUnLoad) and returns. A slow successful flush and its user-change callbacks can therefore run after component cleanup or even after Bukkit has disabled the plugin, allowing stale work to touch torn-down state; the remainder of teardown must be sequenced after deferred retirement without blocking the server thread.

There was a problem hiding this comment.
If a MySQL-backed runtime remains active while reloadAdvancedCore(false) reloads StorageType as SQLite, the backend is now intentionally pinned to MySQL, but this shutdown callback consults the newly reloaded option and skips plugin.getMysql().close(). The shared backend's close() is explicitly non-owning and no other shutdown path closes that connection, so plugin disable/reload leaks the actual MySQL owner; capture the initialized backend type or connection rather than using mutable configuration here.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Guard the final timer wait on deferred retirement.
When Bukkit shutdown runs on the primary thread and userStorageRetirement is incomplete, canBlockForPreExecutorShutdown() is false. awaitCleanup returns false, so sharedRetirementFinished is false and the synchronous shutdown sequence does not shut down the shared timer. AdvancedCoreRuntime.await then calls awaitTermination unconditionally. An active timer can block the primary thread for the full one-second timeout. The deferred-completion callback may terminate the timer first, but this path can still wait.
Proposed fix
- await(platform.getTimer(), 1, TimeUnit.SECONDS);
+ if (sharedRetirementFinished) await(platform.getTimer(), 1, TimeUnit.SECONDS);📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In
`@AdvancedCore/src/main/java/com/bencodez/advancedcore/core/runtime/AdvancedCoreRuntime.java`
at line 70, Guard the final platform timer wait in AdvancedCoreRuntime.await so
it runs only when shared timer retirement has completed. Preserve deferred
retirement when awaitCleanup returns false, and avoid calling awaitTermination
on the primary thread while userStorageRetirement remains incomplete.

Scope
Second Fabric/Forge/NeoForge preparation step, stacked on #324.
SharedUserDataRuntimefor UUID-based access, startup enumeration, cache population, queued changes, flush, provider replacement, and shutdown.UserDataFetchModesource-selection flags, including temp-cache precedence and non-waiting storage fallback.UserCacheOwner; the runtime does not allocate a second user cache or parallel user record.BukkitUserCacheOwner, which reuses the existingUserDataManagermap,UserDataCacheinstances, queued-change ordering, notifications, and batching behavior.Dependency order
Behavior constraints
This PR intentionally leaves player/entity operations in Bukkit-facing code. It does not restore FLAT, introduce a second cache, add a migration system, or change Maven packaging/dependency pins.
The Bukkit cache adapter deliberately lets the existing
UserDataCache.processChanges()remain the owner of notification/write ordering instead of short-circuiting its durability behavior.Validation status
Ready for review at the maintainer's request; not a claim of merge readiness. The normal local repository build environment was unavailable from the implementation session. The headless tests are repository tests, not a live server test. At the ready-for-review check, no PR-triggered GitHub Actions run was returned for head
fda552cea136d285055a59e3f4b39a7ffafdb123; no passing repository build is claimed for this head. Codex code and security reviews started automatically when the draft was marked ready. No duplicate review request was sent.Known remaining integration item
The existing
UserData/UserManagerconstruction path has not yet been switched to instantiate/useSharedUserDataRuntime; those are large, concurrently active files and the implementation session used a connected GitHub write interface requiring whole-file content. The shared lifecycle implementation and Bukkit adapter are present, but existing consumers are not yet delegated through it. This remains an acceptance blocker until that wiring can be safely completed and the full Maven build/review is clean. Marking ready for review does not remove this blocker.No merge/release/deploy is requested.
