Review Comment:
The explicit `mkdirs()` here is redundant — `FileUtil.createTempFile()`
(line 328 below) already calls `parentDir.mkdirs()` internally before creating
the temp file. This block can be removed and simplified to just:
```suggestion
File spoolDir = strategy.resolveSpoolDirectory(exchange);
tempFile = FileUtil.createTempFile("cos", ".tmp", spoolDir);
```
