More fun with default parameters

Seems like the work in GRECLIPSE-1233 is not complete. Mark occurrences is not correct when there are default parameter references coming from other files. Eg-

class C {
    def xxx(a, b = 2) {}
} 

and in another file:

def obj
new C().xxx()
new C().xxx(obj)
new C().xxx(obj, obj)
new C().xxx(obj, obj, obj) 

Select the first, third or fourth method reference and the first, third, and fourth reference highlights. Select the second, and only the second highlights.

The correct behavior is that selecting any method reference should select all other references. This is the behavior that you see when all are inside the same file.
