The expected result is EXPECTED__doc.pdf
My workaround:
To resolve URLs such as "marker-start:url(#TriangleInM)", Batik 1.8 needs
to know the URL of the SVG document it processes.
Therefore in org/apache/fop/apps/FOUserAgent.java, I've replaced:
---
public StreamSource resolveURI(String uri) {
// TODO: What do we want to do when resources aren't found??? We also
need to remove this
// method entirely
try {
// Have to do this so we can resolve data URIs
StreamSource src = new
StreamSource(resourceResolver.getResource(uri));
src.setSystemId(uri);
return src;
} catch (URISyntaxException use) {
return null;
} catch (IOException ioe) {
return null;
}
}

by:
---
public StreamSource resolveURI(String uri) {
// TODO: What do we want to do when resources aren't found??? We also
need to remove this
// method entirely
try {
// Have to do this so we can resolve data URIs
StreamSource src = new
StreamSource(resourceResolver.getResource(uri));
// A systemId is always expected to be absolute.
// Anyway, without this, SVG files using markers
// (e.g. marker-start:url(#TriangleInM)) cannot be rendered.
if (!uri.startsWith("data:")) {
uri =
resourceResolver.getBaseURI().resolve(uri).toASCIIString();
}
src.setSystemId(uri);
return src;
} catch (URISyntaxException use) {
return null;
} catch (IOException ioe) {
return null;
}
}
