>Description:
Run the script below to generate the java code, then compile it.

 $ sh the_script
 $ gcj -C bava/awt/*.java
 bava/awt/Dialog.java: In class `bava.awt.Dialog':
 bava/awt/Dialog.java: In method `bava.awt.Dialog()':
 bava/awt/Dialog.java:4: Can't find method `setLayout(Lbava/awt/BorderLayout;)' in type `bava.awt.Dialog'.
                setLayout(new BorderLayout());

If BorderLayout only extends LayoutManager and not LayoutManager2, everything
is fine. So it seems that the class hierarchy of interfaces are not checked
in arguments.
