A DESCRIPTION OF THE PROBLEM :
The program i have is to rename a file is:

D:\EclipseProjects\springClasses\SpringClasses>cd src\main\java

D:\EclipseProjects\springClasses\SpringClasses\src\main\java>type com\rsa\springclasses\day3\logback\TestRename.java
package com.rsa.springclasses.day3.logback;

import java.io.File;

public class TestRename {
        public static void main(String[] args) {
                File src = new File("D:/EclipseProjects/springClasses/SpringClasses/target/log/application.log");
                boolean success = src.renameTo(new File("D:/EclipseProjects/springClasses/SpringClasses/target/log/application.2016-Aug-21_21:49:55_0.log"));
                System.out.println(success);
        }
}


D:\>cd EclipseProjects\springClasses\SpringClasses\target\classes

D:\EclipseProjects\springClasses\SpringClasses\target\classes>java com.rsa.springclasses.day3.logback.TestRename
false

When I tried this program in debugger,

Entered into: File -> renameTo method
security variable is null
if (this.isInvalid() || dest.isInvalid()) -> false

Entered into: WinNTFileSystem -> rename method
cache.clear() -> done
prefixCache.clear() -> done

Finally called: private native boolean rename0(File f1, File f2);

This is always returning false indicating that file name is not renamed. I double / triple checked via procmon.exe and found that no process holding applicaiton.log file. Even before running my sample program, I rebooted my laptop, logged in as root(administrator), opened cmd only. Let me know if you need any additional information.
