[jdom-interest] Sorting Children, Collections.sort, ComodificationException, etc., etc.

That would work, but IMHO it still be better for setContent to return
something more useful then the parent.  To use setContent you have to
already have the parent.

Guess this would be a good example for ELH's "Pinciple of Least Surpise".
Here I had a hand in the current implementation and was still bitten by
it:)
