RFR: 8259359: javac does not attribute unexpected super constructor invocation qualifier, and may crash

[Guoxiong Li]

Hi all,

Currently, javac doesn't attribute unexpected super constructor invocation qualifier. Please see the following code.

public class SuperConstructorCallInErrorClass extends Undefined1 {
     public SuperConstructorCallInErrorClass(int i) {
         new Undefined2() { public void test(int i) { Undefined3 u; } }.super();  //<-------------------
     }
}

The code `new Undefined2() { public void test(int i) { Undefined3 u; } }` isn't attributed by javac.
If we use options like `-XDshould-stop.at=FLOW -XDdev`, the compiler would crash.

This patch fixes it and adds the corresponding test cases.

Thank you for taking the time to review.

Best Regards.
