Debugger: hot code replace- can not get it to work

here is a sample code

public class Test {
    public static void main(String[] args) throws Exception {
        do {
        } while (true);


I stop at first line, then replace



make hot code replace (recompile), Idea says, 1 class was reloaded, then I run it again (f9)...

The result
1) Change is not taken into effect (it prints 1)
2) Breakpoint does not work anymore... it does not stop.

Win 7 x64, Java 6
Any ideas?

HotSpot limitation - it can't replace a method being executed.
Just extract println() call into separate method and it'll be able to update it.
