Lucee can return the `stackTrace` property on an exception as a Java array
of StackTraceElement objects rather than a simple string. Guard against
this by checking isSimpleValue() before comparing to "" and by serializing
complex values to JSON before inserting.

reservedDate compared against pool.getTimeout() always used the pool's
fixed 60s window, causing jobs with longer per-job timeouts (e.g. 300s) to
be re-grabbed and have attempts incremented while still running.
availableDate is already set to now + jobTimeout at reservation time, so
comparing it against now correctly respects each job's actual timeout.

Fixes both fetchPotentiallyOpenRecords and tryToLockRecords.

…timeout

Three specs covering the core bug fix in DBProvider:
- A reserved job within its own timeout is not re-grabbed
- A reserved job whose timeout has expired is re-grabbed
- A job past the pool timeout but within the job timeout is not re-grabbed

Uses TestBox makePublic() to expose fetchPotentiallyOpenRecords for
direct testing.

…ockRecords guard

ColdBoxAsyncProvider: The thenCompose closure referenced
arguments.currentAttempt which does not exist in the closure scope,
so setCurrentAttempt() never executed for retried jobs. Changed to
check the captured attempts variable instead.

DBProvider.tryToLockRecords: Added whereNotNull(reservedDate) guard
to the availableDate OR branch, consistent with the same fix already
applied to fetchPotentiallyOpenRecords. Ensures only genuinely
timed-out reserved jobs are re-locked.

If dispatchThenJobIfNeeded or dispatchCatchJobIfNeeded threw an
exception (e.g. missing WireBox mapping, connection error), the
finally job would never be dispatched. Wrap both in try/catch so
dispatchFinallyJobIfNeeded always runs, matching the semantic
contract of "finally".

The exception was passed to the job onFailure handler under the
misspelled key "excpetion" instead of "exception", so any job
defining onFailure( exception ) would receive an undefined argument.
Aligns SyncProvider with the AbstractQueueProvider behaviour.

When the marshalJob future's exception handler fails to execute
properly, jobs remain reserved with reservedDate set. Once the
job timeout passes, fetchPotentiallyOpenRecords picks the row up
again with no maxAttempts check, causing unbounded retries
(observed: 29 attempts on a job configured for 3).

Add a defensive guard at pickup time: before incrementing attempts
and dispatching, compare the DB attempts column against
maxAttempts. If exceeded, mark the job as failed and skip.

The marshalJob future was fire-and-forget. Any exception inside
.onException — releaseJob serialization, batch recording, an
interceptor, the job's onFailure hook — was silently absorbed by
the unobserved future, leaving the row reserved and triggering
unbounded timeout-based re-pickups.

Wrap each side-effect in its own try/catch so one failure cannot
prevent the rest from running, and add an outer catch that calls
a new forceFailJob hook as a last-resort terminal kill.

forceFailJob is a no-op on AbstractQueueProvider and overridden
on DBProvider with a minimal UPDATE that sets failedDate and
clears the reservation. It deliberately skips bookkeeping
(onFailure hook, interceptors, batch recording) — it only runs
when the proper failure path itself throws, and the alternative
is the row being retried until manually cleaned up.

…empts integration tests

The inline loop body is pulled into a private processLockedRecord method so integration
tests can make it public and exercise the maxAttempts pre-flight guard in isolation.

If log.error threw in the async thread (e.g. when serialising a MockBox
exception struct), markJobFailed was silently skipped, leaving the row
reserved and the timeout watcher free to re-pick it up indefinitely.
Wrapping the log call in its own try/catch ensures the fallback path to
markJobFailed is always reached regardless of logging failures.

WireBox provider methods (newQuery) are not reliably invocable through
MockBox pass-through in async threads, so the DB write in markJobAsFailedById
silently failed in CI regardless of the log-guarding fix. Switching to a
mock-call assertion — the same technique used by the forceFailJob-fallback
test — verifies the correct code path without depending on the broken DB
write path.

MockBox cannot reliably stub private methods reached through the async
closure's captured variables scope, and its pass-through for WireBox
provider methods (newQuery) is broken in async threads. Replace the
prepareMock approach with a real FailingReleaseDBProvider subclass that
overrides releaseJob to throw — no mocking needed, so newQuery stays a
proper WireBox provider method and the DB write goes through correctly.

Adds tests/resources/app/models/**/*.cfc to the format, format:check,
and format:watch scripts so fixture files like FailingReleaseDBProvider
are checked and formatted consistently with the rest of the codebase.

- Wrap afterJobHook in try/catch so a throwing hook logs via
  logSideEffectFailure and does not flip a successful job to failed
- Rename onFailureExceptionIsExpcetion → onFailureExceptionHasExcpetionKey
  in OnFailureCapturingJob and SyncProviderOnFailureSpec to separate the
  intentional 'excpetion' typo-under-test from the variable naming

…rceptor

memento, properties, exceptionExtendedInfo, exceptionStackTrace, and
exception all map to LONGTEXT in the cbq_failed_jobs schema. Binding them
as CF_SQL_VARCHAR risks truncation or driver errors on large payloads
(e.g. deep stack traces or complex job mementos).
