FIX: System.getproperty("user.name") Returns Null

 Last reviewed: January 29, 1998
Article ID: Q177175
The information in this article applies to:
  • Microsoft Win32 Virtual Machine for Java

SYMPTOMS

 The Microsoft Virtual Machine for Java build 1518 and earlier returns null
while attempting to use System.getProperty("user.name") to determine the users login name.

RESOLUTION

This is a bug and has been fixed in the Microsoft Virtual Machine for Java that ships with the SDK 2.01 for Java.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This bug has been corrected in the Microsoft VM for Java that is provided in the SDK 2.01 for Java.

MORE INFORMATION

Steps to reproduce the problem:

Create a Java Project and include the following class to it: 

   class TestProperty
   {
      public static void main(String args[])
      {
        System.out.println(System.getProperty("user.name"));
      }
   }
With the Microsoft Virtual Machine for Java, this will return null. However with Microsoft Virtual Machine for Java included with the SDK 2.01 for Java, it will correctly return the user's login name.
