Re: [aspectj-dev] Constructor Join Point and Super() constructor

super(..) should never be available in advice.
That I think is a compiler bug.
wrt calling super, does it work to declare the constructor?
Target.new() {
super("hello");
...
}
(If the default constructor is already declared, then you
can't do that.)
Another approach is to replace the calls:
Target around() : call(Target.new()) {
return new Target("hello");
}
You might combine this with the inter-type declaration of
the constructor.
Since super(..) is a special form in Java, that's pretty
much all you can do in AspectJ.
