When you've overridden a class method in some third-party package and then
upgrade to a later version of that package, it sometimes turns out that the
method has been removed, or renamed, or given some additional parameters. It's
much nicer to get a compile-time error than to eventually discover that your
overriding method is no longer being called. This has happened to me more than
once with Hibernate.

How come this "BBS" is included in some loop, regurgitating loads of posts and
disregarding standards? Who invited it? For example, Arne Vajhoejs name in his
From headers is sent in 8-bit code.
