Eclipse : Conditional Break Points inside Eclipse

I have written a small Sample program to see about Eclipse Conditional Break Points 

public class Test {
    public static void main(String args[]) {
        System.out.println("One3");
        String str = null;
        String name = str;
    }
}

And inside the Eclipse Debugger Perspective , under BreakPoints , i have set condition as shown str!=null

Please see the image here of it . http://tinypic.com/view.php?pic=kdrc0g&s=5

From this what i understood is that , the condition (str!=null) doesn't meet the code , so the debugger will give a warning .

Please tell me if my understanding is correct ??

In Debug mode, when the condition is satisfied, the code execution will pause at that point, allowing you to observe variable values, continue execution step by step and such.

Is the break point defined before the str declaration ? If it's the case, it's normal this break point doesn't work because the str string is unknow.

You're putting a breakpoint with a condition on the variable str at a location where there is no variable str. So obviously, the condition is impossible to evaluate.

If the breakpoint was on the last line, then it would be valid.
