Example:

    public class Foo
    {
        public Foo(int n) { }
    }
    
    public class Bar extends Foo
    {
        private final String s;
        private final boolean b;        
    }

Code completion within Bar proposes to generate Bar() or Bar(String s, boolean b), but the generated constructors will 
be insufficient because the super constructor requires an argument. It's often the case that super constructor 
arguments are also arguments passed to the current constructor, hence it would be useful to also propose the generation 
of Bar(int n) and Bar(int n, String s, boolean b) in the example above.

This would also be useful regardless of the presence of instance fields, for example in subclasses of 
java.lang.Exception, which often have the same four constructors as java.lang.Exception, which then would be available 
for automatic generation.
