Description
When the parameters and return types for FileChannel.transfer{From,To} and
{Scatter,Gather}ingByteChannel were revised from int to long, only a minimum set
of changes was done.  We need to verify that the actual implementations can handle large files.  

For an example of potential problems, see the implementation of
sun.io.ch.FileChannelImpl.transferTo().  It is impossible for that method to 
ever return anything larger than Integer.MAX_VALUE.

EVALUATION The spec makes no guarantee about how many bytes are processed, so it is perfectly legal to always return values that fit into an integer. Therefore I am changing this to an RFE for Mantis or Tiger. ###@###.### 2002-04-09
