File is updated with two consecutive transferFrom() operations.
First operation writes 'n' bytes and second operation writes 'm' bytes to underlying file.

FileChannel.size() returns correct size of underlying file.
However, File.length() returns 'n' (rather than actual file size).

This fails on Windows 2000 professional.

Works fine on Solaris, Windows NT, Linyx, Windows 98.

--------- part of test code transferFrom.java: xferTest04() ----------
// FileChannel fcS1, fcS2, fcD ;

//get read file channel for the file
fcS1 = Helper.openReadFileChannel(new File(src1FileName));

//get read file channel for the file
fcS2 = Helper.openReadFileChannel(new File(src2FileName));


File file = new File (dstFileName) ;

// get filechannel for the dst file.
fcD = Helper.openRWFileChannel(dstFileName) ;

bytesToWrite = srcData.length ;
startPosition = 0 ;

bytesWritten = fcD.transferFrom(fcS1, startPosition, bytesToWrite);

// verify that first transfer operation is fine.
System.out.println("bytesWritten=" + bytesWritten);
System.out.println("fcD.size()=" + fcD.size());

//fsize = (int) file.length() ;
//System.out.println("file.length()=" + fsize);

bytesToWrite = srcData.length / 2 ;
startPosition = (srcData.length / 2) + (srcData.length / 4) ;

bytesWritten = fcD.transferFrom(fcS2, startPosition, bytesToWrite);
            // verify that first transfer operation is fine.
System.out.println("bytesWritten=" + bytesWritten);
System.out.println("fcD.size()=" + fcD.size());

fsize = (int) file.length() ;
System.out.println("file.length()=" + fsize);

FileInputStream fis = new FileInputStream (file) ;
favail = fis.available() ;
System.out.println("fis.available()=" + favail);

------------ results on windows 2000 ------------
bytesWritten=7868
fcD.size()=7868
file.length()=7868
bytesWritten=3934
fcD.size()=9835
file.length()=7868 <<<< should be 9835
fis.available()=9835

----------- result on other platforms -----------
