Team-HomeGUI Plugin

[1.3.0] — Bug-fix & Feature Release

New Feature

• Confirm-Delete Home GUI — clicking the red dye (delete) button in the Home GUI now opens a 27-slot confirmation dialog instead of deleting instantly.
  • Slot 11 (user-facing 12) → 🔴 Red glass pane "No" — cancel
  • Slot 13 (user-facing 14) → 🛏 Red bed "Delete Home?" — centre icon
  • Slot 15 (user-facing 16) → 🟢 Lime glass pane "Yes" — confirm permanent deletion

Critical Bug Fixes

• NPE crash when opening Home GUI — loc.getWorld().getName() was called without a null check; if a world was deleted or unloaded after a home was saved, opening the GUI caused a NullPointerException and crashed the inventory for that player. Now shows "World no longer exists" gracefully for both personal homes and team home.
• Race condition in HomeManager — inner HashMap<String, Location> was not thread-safe; the async save thread iterating it while the main thread wrote to it could cause ConcurrentModificationException and silent data loss. Changed to ConcurrentHashMap for inner maps.

Bug Fixes — Logic

• Mass message-key mismatch — dozens of plugin.msg(key) calls used keys that did not exist in team-config.yml, causing players to see raw "Message not found: <key>" strings. All handlers now reference the correct existing keys or new keys added in this release:
  • TeamHandler: invite-no-permission, invite-already-in-team, leave-success, player-left-team, player-not-in-team, kick-no-permission, cannot-kick-owner, kick-broadcast (updated placeholders {kicker} / {kicked})
  • ChatHandler: chat-already-enabled, chat-already-disabled; team-message format now reads settings.chat-format (was hardcoded missing key "team-chat-format") and correctly replaces {team} and calls TeamPlugin.color()
  • SettingsHandler: all promote / demote / transfer / name / invite messages now match config keys; "settings-name-success", "settings-invite-changed", "settings-transfer-success/received/broadcast" and "settings-promote-self-error" added
  • AdminHandler: "wrong-password", "admin-team-already-exists", "admin-ban-success", "admin-unban-success", "admin-add-success/target", "admin-already-banned", "admin-not-banned", "admin-disbanned-target", "admin-remove-team-success" aligned
  • ListHandler: "list-entry" and "list-footer" added to config
• SettingsHandler.handleAdminSettings() always returned "team not found" — the handler was reading args[1] (which contains the literal string "settings") instead of args[2] as the team ID. Fixed all admin-settings argument indices accordingly.
• Admin /team admin settings sub-command was unreachable — AdminHandler.handleAdmin() had no "settings" case in its switch statement. Added routing to SettingsHandler.
• Team.canInvite() ignored Admin role — the public method only checked Owner and membersCanInvite, making the Admin role unable to invite when membersCanInvite=false. Now consistent with TeamHandler.canInvite().
• No max-members enforcement on invite — TeamHandler.handleInvite() never checked the configured settings.max-members limit. Teams could grow without bound. Fixed.
• Self-invite not caught — a player could invite themselves; added explicit check using existing "invite-self-error" config key.
• Pending-invite not checked — a target with a pending invite from any team could receive multiple invites. Now uses the existing "invite-already-pending" key.
• GUISlots enum had duplicate slot values — DELETE_DYE_* and SET_DYE_* both pointed to slots 29–33 (which were never used; real action slots are 20–24). Replaced with ACTION_1..5 + new CONFIRM_NO / CONFIRM_BED / CONFIRM_YES slots.
• ListHandler returned teams in random order — ConcurrentHashMap.values() has no guaranteed iteration order; added alphabetical sort.

Bug Fixes — Performance / Safety

• Team.getOwnerName() could block the main thread — Bukkit.getOfflinePlayer(UUID) may perform disk I/O to read playerdata files. Now checks the online-player cache first, then getOfflinePlayerIfCached() (no I/O), and only falls back to the disk call for completely unknown players.
• WarmupListener did not restore custom walk/fly speed — after a warmup the speed was always reset to Bukkit defaults (0.2 / 0.1), overriding server-rank speed multipliers. The actual speeds are now saved before freezing and restored on cancel or completion.
• HomeManager.getHomeNames() returned a mutable live view — callers iterating the result while a concurrent modification occurred could get ConcurrentModificationException. Now returns Set.copyOf().
• Home name validation inconsistency — HomeService allowed - and had no length cap, while HomeHandler did not allow - and enforced 16 chars. Unified to the stricter ^[a-zA-Z0-9_]{1,16}$ pattern across both paths.
• gui.show-coordinates default mismatch — Java fallback was true while the config file default is false. Changed Java fallback to false.
