Description
tested in build 1.4.1-beta-b02 :

In win2000 , the transferTo() does not transfer files > than 2^31-1 bytes.
it throws an exception of "java.io.IOException: The parameter is incorrect"

In solaris8 , Bytes transfered to Target channel are 2^31-1 even if the 
source channel file is greater than 2^31-1

In LinuxRH7.1 , it gives an error of java.io.IOException: Input/output error

The testcase is attached

WORK AROUND On Windows, reduce the number of bytes transferred at one time. Transferring a smaller number of bytes works even at offsets beyond 2^31-1. ###@###.### 2002-10-28

EVALUATION The spec allows such transfers to occur in chunks of less than 2^31-1 bytes. The exceptions are bugs that will be addressed in Mantis. ###@###.### 2002-05-24 We can't fix this on Linux in Mantis since some Linux kernels can't do positional writes or truncates beyond 2^31-1. Windows has similiar OS issues with large files and large offsets although transferring a smaller amount of bytes succeeds even at large offsets. ###@###.### 2002-10-28
