Validate dependent features after a ProtocolLib maintenance restart
Applies to: ProtocolLib; match the linked maintainer documentation to your installed platform and release.
Documentation checked .
Some packet-dependent failures appear only when a player opens a menu, changes equipment or enters a display area. A clean startup is therefore one checkpoint, not the whole maintenance test. List the features that actually depend on ProtocolLib and exercise them deliberately.
Record the starting point
Identify your installed ProtocolLib consumers from their documentation and startup output. Choose a normal player account and a compact test route. Save the previous artifacts and configuration before the maintenance restart so a regression has a known recovery path.
Work through the change
- Write one observable action for each important dependent feature, such as opening a configured menu or viewing a packet-based display. Use your actual plugins rather than copying an unrelated server's checklist.
- Stop normally, apply the planned compatible release and start the service. Read the first startup errors before inviting testers to the action route.
- Perform the checklist with ordinary permissions, recording timestamps. Repeat an action after reconnecting if it depends on login state or cached client data.
- Compare item counts, displayed content and permission boundaries with the pre-change behaviour. Keep an eye on the console while the action runs, not only after the player leaves.
Check the result
Each critical dependent feature should produce its intended result without fresh listener exceptions. Record skipped checks explicitly, especially integrations that require another player or a scheduled event. A staff account bypass can conceal a permission or menu problem.
If the result differs
If one action fails, isolate its dependent plugin and gather its complete exception. Avoid changing every packet consumer simultaneously. A clean idle log followed by a failing menu click should be reported as an action-specific regression, not a successful update.
Restore the previous compatible artifact set if a critical feature cannot be recovered within the window. Remove disposable test items only after checking their counts. Keep the checklist for the next update; no server reinstall or world replacement belongs in this validation.
