## What's Changed `FromSchemaByteArray()` in `dataset/src/main/cpp/jni_util.cc` acquires the Java byte-array elements via `GetByteArrayElements()`, but the matching `ReleaseByteArrayElements()` call was only reached on the success path. When `arrow::ipc::ReadSchema()` failed, `ARROW_ASSIGN_OR_RAISE` returned early and skipped the release, leaking the pinned/copied array buffer on every call with malformed or incompatible serialized schema bytes (e.g. via the public `createDataset()` method). This change releases the elements through an RAII guard (a `std::unique_ptr` with a custom deleter) so they are always freed on every exit path - success or error, and remains correct if additional early returns are added in the future. Closes #1205. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
