        Internal copy file method. This caches the original file length, and an IOException will be thrown if the output file length is different from the current input file length. So it may fail if the file changes size. It may also fail with "IllegalArgumentException: Negative size" if the input file is truncated part way through copying the data and the new file size is less than the current position.

        Parameters:
        srcFile - - the validated source file, may not be null
        destFile - - the validated destination file, may not be null
        preserveFileDate - whether to preserve the file date
        Throws:
        java.io.IOException - if an error occurs
        java.io.IOException - if the output file length is not the same as the input file length after the copy completes
        java.lang.IllegalArgumentException - "Negative size" if the file is truncated so that the size is less than the position
