I am fairly certain that is the "intended behaviour" since the workdir
for your desktop is most likely your home dir (and I assumed "Sun java 6
Runtime" refers to a menu or "Open with ...").

You should be able to reproduce this with the following in the terminal:

 $ cd ~
 $ java -jar /abs/path/to/abc_program.jar

In this case "user.dir" should also be your home-dir; if you want to
locate the path to the jar file, then you need something like:

  this.getClass().getProtectionDomain().getCodeSource().getLocation();
  SomeClass.class.getProtectionDomain().getCodeSource().getLocation();

(possibly with some null checks in between).
