Description

The private doCopyFile method of FileUtils does a comparison between the source and destination file sizes after the data has been copied.

If the destination file has been removed, renamed, or otherwise no more accessible (remote share no more available) between the finally block and the size comparison the destFile.length() returns zero. If the source file is not zero bytes in size an exception with the message "Failed to copy full contents from '" + srcFile + "' to '" + destFile " will be thrown.
