             Summary: Could FileUtils.copyFile not be flushed and synced when comparing file sizes?
                 Key: IO-544
                 URL: https://issues.apache.org/jira/browse/IO-544
             Project: Commons IO
          Issue Type: Bug
          Components: Utilities
    Affects Versions: 2.5
         Environment: Win Server 2008, x86
            Reporter: Sean Poulter


I've been struggling to troubleshoot intermittent IOExceptions thrown from FileUtils.doCopyFile when copying 2-4KB files from a local temporary file to a network drive. Despite the error, the file appears on the network drive when I check. Should the output channel/buffer be forced/flushed before closing, and synchronized before comparing the file lengths? It's a rather intermittent issue on a relatively high throughput PC so I'd expect there to be more IO latency than normal.

Thanks,
Sean
