Worked on the EssentialsX/Essentials repository to enhance server reliability by addressing a critical bug in the player respawn system. Focused on backend development using Java and the Bukkit API, the work involved updating version checks in EssentialsSpawnPlayerListener to align with changes introduced in Bukkit 1.20.4. This targeted fix resolved a NoSuchMethodException in Player.getRespawnLocation, preventing runtime errors during player respawn events. The approach included refining respawn location logic to ensure consistent player experiences and reduce edge-case crashes. The contribution improved compatibility with the latest Bukkit release, supporting smoother server operations and maintaining stability for multiplayer environments.
