如何防止JsonWriter在序列化多维数组时添加过多换行符？

JsonWriter writer = new JsonWriter();
writer.setIndent(0);

int[][] multiDimArray = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};
int[] flatArray = Arrays.stream(multiDimArray)
                        .flatMapToInt(Arrays::stream)
                        .toArray();

JsonWriter writer = new JsonWriter();
writer.writeValue(flatArray);

public class CustomJsonWriter extends JsonWriter {
    @Override
    public void writeValue(Object value) {
        if (value instanceof int[][]) {
            int[][] multiDimArray = (int[][]) value;
            for (int[] row : multiDimArray) {
                writeArrayRow(row);
            }
        } else {
            super.writeValue(value);
        }
    }

    private void writeArrayRow(int[] row) {
        writeArrayStart();
        for (int i = 0; i < row.length; i++) {
            writeValue(row[i]);
            if (i < row.length - 1) {
                writeArraySeparator();
            }
        }
        writeArrayEnd();
    }
}

int[][] multiDimArray = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};
CustomJsonWriter writer = new CustomJsonWriter();
writer.writeValue(multiDimArray);
