Bug Description:
Insufficient System Resources When Copying Large Files with NIO FileChannels

This is a duplicate of bug 4938442 which was closed as not a defect.

This has been tested on many systems on completely different Networks and
does not work on any of them.

Just retested using 1.6.0_13 and this problem still exists.

The problem can be reproduced when copying a file > 64 MB to a shared directory.
Example: On Win_XP machine copying jdk-6u13-windows-i586-p.exe as the file (about 74.9 MB) to a remote shared directory on a Linux server.

Test program:

import static java.lang.System.*;
import java.io.*;
import java.nio.channels.*;

public class Test {
  public static void main(String args[]) {
    File sourceFile = new File("c:/test.exe"); // some local file that is larger than 64 MB
    File destinationFile = new File("s:/test.exe"); // where the destination is a shared directory on a remote machine
    if (destinationFile.exists()) {
      destinationFile.delete();
    }
    try {
      FileInputStream input = new FileInputStream(sourceFile);
      try {
        FileOutputStream output = new FileOutputStream(destinationFile);
        try {
          FileChannel inputChannel = input.getChannel();
          long size = inputChannel.size();
          if (size != inputChannel.transferTo(0, size, output.getChannel())) {
            throw new IOException("Incomplete Transfer");
          }
        }
        finally {
          output.close();
        }
      }
      finally {
        input.close();
      }
    }
    catch (IOException ex) {
      out.println(ex);
    }
  }
}
