 ## Common Gotchas
-- **Develocity build cache**: The project uses Gradle Enterprise/Develocity Maven extension (`.mvn/extensions.xml`) which caches compiled classes across builds. Always use `clean` in Maven commands to bust this cache when source files change, especially in CI publish steps
+- **Develocity build cache (REMOVED)**: The Develocity Maven extension was removed from `.mvn/extensions.xml` because its local build cache persisted stale compiled classes across GitHub Actions runs (restored via `setup-java` Maven cache). Neither `clean` nor `-Ddevelocity.cache.local.enabled=false` prevented it. v1.3.0 and v1.3.1 were published with stale bytecode as a result. CI now purges `~/.m2/repository/org/apache/arrow/memory-netty-buffer-patch` before builds and has a bytecode verification step.
 - Rebuilding only `memory-netty-buffer-patch` is NOT enough — must rebuild the full shaded driver with `-am`
 - The shaded JAR relocates all classes under `org.apache.arrow.driver.jdbc.shaded.*`
 - JAR timestamps inside shaded JARs show original compile time, not rebuild time — don't trust them
