Kayos 77162c3ebd fix: sync with monorepo canOcclude() fix, add [1.21.1] inline comments 
CRITICAL FIX: Gitea repo was missing the canOcclude()/isAir() changes that
prevent Guava LoadingCache deadlock with modernfix/ferritecore.

Added inline comments to explain all API changes:
- canOcclude()/isAir() deadlock prevention (lines 248, 259)
- ServerTickEvent.Post event API change (line 919)
- getLatestChunk()/getPersistedStatus() chunk API (lines 1860, 1863)
- NBT contains() reimplementation (line 30)
- NBT getAsString() null safety (line 96)

This is now fully synced with the tested/working monorepo version.

Dynmap — NeoForge 1.21.1 Port

Port of Dynmap to NeoForge 21.1.219 / Minecraft 1.21.1.

This standalone build is used for deployment on an ATM10 server. The goal is to eventually submit this as a PR back to the upstream webbukkit/dynmap repository.

Building

Requires Java 21 and Docker (build container: dynmap-neoforge-build).

# Inside build container
cd /workspace
./gradlew shadowJar --no-daemon

Output: build/libs/Dynmap-neoforge-1.21.1-3.7-SNAPSHOT-Dev-all.jar

Memory notes

  • Gradle daemon heap: capped at -Xmx2g (see gradle.properties)
  • forked javac: capped at -Xmx3g (see build.gradle)
  • Without these caps, JVM defaults to 25% of host RAM — causes OOM on high-RAM hosts

Changes from upstream neoforge-1.20.6

See CHANGES.md for the full changelog.

Test status

Environment Result
Vanilla NeoForge 1.21.1 (clean server) ✅ Passes
ATM10 5.5 (445 mods, NeoForge 21.1.219) ✅ Passes

Deployment

Copy the fat jar into the server's mods/ directory. Remove any old Dynmap*.jar first.

docker cp build/libs/Dynmap-neoforge-1.21.1-3.7-SNAPSHOT-Dev-all.jar <container>:/data/mods/

Note: Always remove old jars before copying a new one. The container data volume may retain old versions.

Containers (internal, Lucy/Unraid)

Container Purpose Ports

PR Plan

Once ATM10 testing is confirmed:

  1. Mirror all changes to monorepo (dynmap-upstream/neoforge-1.21.1/)
  2. Push to Cobbert/dynmap fork on GitHub
  3. Open PR: Cobbert/dynmap:neoforge-1.21.1 → webbukkit/dynmap:neoforge

PR description draft is in DYNMAP.md (workspace copy).
