Structural Search - calls of super() in overriden method

Hi

How can I find all occurrences of:

overrides of method XYZ.foo() that call super.foo() in overriden method foo().

e.g.
class XYZ {
public void foo() {
...
}
}

class Bar extends XYZ {
public void foo() {
super.foo(); // that's what I want to find!
.....
}

...
}

Thanks for your help!
