FULL PRODUCT VERSION :
java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)
Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)

FULL OPERATING SYSTEM VERSION :NT 4.0,Service pack 3,build 1381


EXTRA RELEVANT SYSTEM CONFIGURATION :
All machines where this bug was reproducble had c:,d:e:
drives only

A DESCRIPTION OF THE PROBLEM :
It seems if I create a file abcd:abcd on the D DRIVE(only)
a 0 kb file is created with the name abcd

If I try to create a file by the name abcd: or abcd?abcd on
the D: drive, Then an exception is thrown(Expected
behaviour)

For all other restricted charecters (ie charecters that
cannot be included in filenames) exception is thrown in
both cases mentioned above(expected).

The problem defined above happens IN CASE WE CREATE THE
FILE IN THE D: DRIVE ONLY.

But then there is a twist......
This problem seems to happen only with machines that are
partitioned as c:,d:,e:

And this does not seem to be an an issue with the service
pack as I was able to reproduce the same bug on two
machines with service packs 3 and 6.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
try to create a file abcd:abcd with code below on your D:
drive (donot create any subdirectories).run on the dos
prompt
file abcd is created ,0kb size

try to create a file abcd?abcd ,exception is thrown at
runtime




EXPECTED VERSUS ACTUAL BEHAVIOR :
no exception is thrown and 0kb file created in d; drive.
change the file name to say abcd?abcd in the code above
An exception is thrown at runtime (expected).
Note:-Note this bug is reproducible on machines with hard
drives c:,d:& e:

This bug can be reproduced always.

---------- BEGIN SOURCE ----------
create a java file with the following code on your D: drive (do not create any
subdirectories).run on the dos prompt

import java.io.*;
 public class Class1 extends Object {

  
  public Class1()
 {
  }

  public static void main(String[] args)
   {
      try
      {
      File outputFile = new File("abcd:ddd");
      Writer textWriter = new BufferedWriter(new FileWriter(outputFile));
      textWriter.write("Write Test");
      textWriter.close();
      }
      catch(Exception e)
      {
       e.printStackTrace();
      }
   }
}
