Consider the following:

void m(String str, List list, Number n) { }
void test(Tuple3<String,List,Long> tuple) {
  m(*tuple)
}
static void sm(Number n) { }
List<Number> numbers
sm(numbers)

When exploring alternatives for GROOVY-11060, some weak points in type inferencing were discovered. "m(*tuple)" is an example of spread arguments; it is shown as unknown (underlined). "sm(numbers)" matches the number of parameters and so StaticImportVisitor transforms it to a StaticMethodCallException. From there, a mismatch between arguments and parameters caused a breakdown in type inferencing for the remainder of the method.
