Hmm
the code we were looking at was:
class MyFbPanel extends FeedbackPanel {
private final Component component;
MyFbPanel(String id, Component c) {
super(id);
this.component = c;
}
protected IFeedbackMessageFilter getFeedbackMessageFilter()
{
return new ComponentFeedbackMessageFilter(component);
}
}
This is an actual documented Java gotcha, discussed in the JavaOne
presentation More Java Puzzlers, by Neal Gafter and Joshua Blog.
public class JavaPuzzler {
public static void main(String[] args) {
new B("Hello").print();
}
public static abstract class A {
public A() {
print();
}
protected abstract void print();
}
public static class B extends A {
final String foo;
public B(String f) {
super();
this.foo = f;
}
protected void print() {
System.out.println("foo = " + foo);
}
}
}
What do you expect on the console here?
