PD4ML implements its own basic SVG renderer, and also allows you to use third-party libraries for the task. If it finds Apache Batik SVG Toolkit among the available libraries, it will automatically switch to it.
Batik tries to implement most of the features of SVG. But, unfortunately, it is very sensitive to even minor file format errors, and there is no way to change its error policy: it always throws exceptions, and there is no switch to turn them into warnings, for example.
In such cases, the best workaround would be to disable Batik and let the built-in SVG engine do the rendering.
Java code to disable Batik:
com.pd4ml.plugins.BatikSvgCustomTag.disable = true;
