Description

The current implementation of writeClip(Shape) of PDFGraphics2D checks whether the given clipping shape is empty. But if the shape has no points (i.e. shape.getPathIterator(...).isDone() returns true) there will only the instructions W n written to the pdf page content stream.
The attached patch will fix this by checking if the PathIterator has at least one segment. If not, it will return without doing anything.
