Build ID: I20070209-1006

Steps To Reproduce:
1. compile the following program
2. or comment the first line of the main and uncomment
   the second line

public class EclipseBug3 {
    <T> EclipseBug3(T t) { }
    
    class A {
      <T> A(T t) { }
    }
    
    public static void main(String[] args) {
      new <?> EclipseBug3(null);
      //new EclipseBug3(null).new <?> A(null);
    }
}

More information:
Using a wildcard as type argument is rejected by the JLS
but eclipse compiler doesn't handle this case.

A call to a parametrized constructor with a wildcard
raises the following exception :
