Is it, somehow, possible to render the Voronoi Treemap into a concave Polygon?

The tree I am trying to visualise results in the following exceptions:

I cannot attach files to issues here, but if you want to reproduce this I'd be happy to send you an XStream XML serialisation of the tree list that causes the fault.
