File size greater than 2 gig causes a failure to read size.

[gap]

The code below will show the failure.
Note that the config.sys file will need to be greater than 2 gig for the test.

package filetest;

public class FileSize {
public FileSize() {

super();

}
public static void main(String[] args) {

FileSize f = new FileSize();
f.run();

}
public void run() {

String fname = "c:
config.sys";
try {

java.io.File fl = new java.io.File(fname);
long flz = -1;
try {

flz = fl.length();

} catch (Exception e) {

System.out.println("File error getting length:" + e.toString());

}
System.out.println("File length:" + flz);
java.io.RandomAccessFile rf = new java.io.RandomAccessFile(fname, "r");
flz = -1;
try {

flz = rf.length();

} catch (Exception e) {

System.out.println("RandomAccessFile error getting length:" + e.toString());

}
System.out.println("RandomAccessFile length:" + flz);
rf.close();

} catch (Exception ee) {

System.out.println("error:" + ee);

}

}
}
