G1HeapUncommitPercent is not available in this JRE build. The
MinHeapFreeRatio=10 and MaxHeapFreeRatio=20 flags are sufficient
to keep JVM committed heap from growing unbounded after uploads.
-XX:MinHeapFreeRatio=10 -XX:MaxHeapFreeRatio=20 -XX:G1HeapUncommitPercent=5
After large game uploads, the JVM committed heap stays high. These flags tell
G1GC to release free heap pages back to the OS after GC cycles, so Docker
memory usage drops back toward baseline instead of staying at peak.
Revert to commit 8108a66 (cue file fix + CD mounting fixes) and
apply only the Dockerfile JVM memory limit. All other changes
(StaticResource Range support, FileChannel transferTo) reverted.
- Replaced Go stdlib server with Quarkus (RESTEasy Reactive + Jackson)
- 7 Java classes: Game POJO, GameService (JSON file I/O), 4 REST resources, static file serving
- Same JSON-per-game storage, same ZIP upload + bundle creation
- Same Svelte frontend (unchanged), built into the JAR via maven-resources-plugin
- Multi-stage Dockerfile: Node → Maven → JRE runtime
