SYMPTOMS
The Microsoft virtual machine (Microsoft VM) 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 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 that is provided in the SDK 2.01 for Java.



MORE INFORMATION
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 earlier Microsoft VMs, this will return null. However with the Microsoft VM included with the SDK 2.01 for Java, it will correctly return the user's login name.
