              The NoninvertibleTransformException stack trace is a little verbose and normally doesn't cause a problem. In this particular case the the pdf is specifying a

              {0,0,0,0,0,0}

              matrix and thus the error report when creating the inverse. The code does however return the Identity transformation when the error is thrown.

              The rendering failure occurs because of a missing clip bounds during the painting of the textSprite. I've added a null pointer check to make sure the intersection calculation only occurs on a valid shape. After these changes the PDF is rendering correctly.
