> Following code reproduces this behavior when run in jdk-7 vs jdk-6. Jdk-7 produces -0.004
while, jdk-6 produces -0.0040.

> public class Main {
>   public static void main(String[] a) throws Exception {
>      double val = 0.004;
>      System.out.println("Value = "+val);
>   }
> }
> {code}
> This happens to be a bug in jdk6, that has been fixed in jdk7.
