SBML Reaction glyphs missing curve segment result in NullPointer exception
Reaction glyphs missing curve segment result in NullPointer exception, however, the curve segment is not mandatory.
SBML layout package specs: "The Curve is is optional, and when not present the dimensions of the inherited BoundingBox describes the center section, by storing its position and dimension"
The attached file is an example of a valid SBML document without the curve. The bounding box in reaction glyph was automatically generated by libSBML.
