########## flink/v1.18/flink/src/main/java/org/apache/iceberg/flink/source/split/IcebergSourceSplit.java: ########## @@ -147,7 +147,7 @@ byte[] serializeV2() throws IOException { for (FileScanTask fileScanTask : fileScanTasks) { String taskJson = FileScanTaskParser.toJson(fileScanTask); - out.writeUTF(taskJson); + writeBytes(out, taskJson); Review Comment: The reason why I don't use out.writeBytes here is because it is buggy. The position with buffer is already incremented by 1 [in here](https://github.com/apache/flink/blob/master/flink-core/src/main/java/org/apache/flink/core/memory/DataOutputSerializer.java#L161) ([Actual place](https://github.com/apache/flink/blob/master/flink-core/src/main/java/org/apache/flink/core/memory/DataOutputSerializer.java#L140) where the increment happens) and it is incremented by the whole size once again [in here](https://github.com/apache/flink/blob/master/flink-core/src/main/java/org/apache/flink/core/memory/DataOutputSerializer.java#L163) which makes it problematic. So I had to take some inspiration from that code and introduce a custom version of it in the class further down. -- This is an automated message from the Apache Git Service.
