In principle this is the same kind of example as Tom's.

It has already been established by now, that this calling
of virtual methods from the c'tor *can* be used with caution
such that it doesn't necessarily lead to bugs.
Also, that alternatives exist, even though they may appear
to be less convenient at times.

What's left open and would interest me is, if this pattern is
already used in any of the big Java-based projects. E.g. a publically
accessible javadoc of the API of a lib documenting some protected 
method to be "called from some superclass constructor and thus
the implementation should not assume 'this' instance to be 
initialized to any degree." 

Not that this existence or non-existence would have any real
impact on Java's future, of course...
