JustAFK v1.0.1 — Extended Version Compatibility
JustAFK 1.0.1 greatly expands server compatibility while keeping Paper 26.2 as the primary platform.
The AFK detection rules and player-facing behavior remain unchanged. This release focuses on making the same lightweight JAR usable across many more Minecraft versions and Bukkit-compatible server platforms.
Highlights
- Expanded compatibility from Minecraft 1.8.8 through 26.2
- Added Java 8-compatible bytecode
- Kept Paper 26.2 as the primary API target
- Added compatibility validation against Spigot 1.8.8
- Added native Folia scheduler support across the supported Folia range
- Improved compatibility with older Bukkit YAML implementations
- Added stronger automated compatibility checks
- No configuration migration required
- No runtime dependencies
Compatibility
| Platform | Versions |
|---|---|
| Paper | 1.8.8–26.2 |
| Purpur | 1.14.1–26.2 |
| Folia | 1.19.4–26.2 |
| Spigot / CraftBukkit | 1.8.8–26.2, best-effort |
| Sponge | Not supported |
| BungeeCord / Velocity / Waterfall | Not supported |
Folia 26.2 does not currently have a public server build. The Folia scheduler implementation was runtime-tested on the latest available Folia 26.1.2 build.
Technical changes
- Compiles against Paper API 26.2 build 84
- Compatibility-compiles against Spigot API 1.8.8
- Produces Java 8 class files
- Verifies bytecode parity between Paper and Spigot builds
- Loads YAML comment support reflectively when available
- Verifies that no runtime dependencies are declared
- Includes additional regression tests for compatibility-sensitive classes
Validation
- 11 automated tests passed
- Paper 1.8.8 startup and plugin lifecycle tested
- Paper 26.2 startup and plugin activation tested
- Purpur 26.2 plugin lifecycle tested
- Folia 26.1.2 scheduler and plugin lifecycle tested
- All 20 release classes verified as Java 8 bytecode
Updating from 1.0.0
- Stop the server.
- Replace
JustAFK-1.0.0.jarwithJustAFK-1.0.1.jar. - Start the server.
Existing configuration files remain compatible and do not need to be regenerated.
Java requirements
The plugin JAR uses Java 8-compatible bytecode, but the server must still run with the Java version required by its Minecraft version.
For example, Paper 26.2 requires Java 25.
