----------------------------------------------------------
As I mentioned in the previous comment: there should be two lines but Acrobat
Reader shows only one. Do you see two diagonal lines in AR or only one?
Also, there is no error popup when opening the attached file but the end result
is the same -- the graphics rendering stops once Acrobat encounters a shape
with a miter limit below 1.0

As I mentioned in the previous comment: there should be two lines but
Acrobat Reader shows only one. Do you see two diagonal lines in AR or only one?
Also, there is no error described above as I couldn't get it to display one
with this simple example (the original PDF was generated using a 3rd party
library) -- This is just a clarification as there is no error popup when
opening the attached file yet the end result is the same -- the graphics
rendering stops once Acrobat encounters a shape with a miter limit below 1.0
> Stroke miter limit is not clamped when writing PDFs

> org.apache.fop.svg.PDFGraphics2D line 1240 (as of SVN revision 148001 [1]) is:
> float ml = bs.getMiterLimit();
> but should be (or equivalent):
> float ml = Math.max(1.0f, bs.getMiterLimit());
> Acrobat Reader (on all platforms) refuses to load graphics data after
> encountering miter limit < 1.0 and reports an error.
> I can't find a reference to the valid range in the PDF spec but Inkscape also
> had a problem with values less than 1.0 [2] and SVG spec mandates values >=
> 1.0 as well [3] so clamping the value to 1.0 or more seems like the right
> thing to do.
