Description

This code:
String fileName = "D:\\Users\\user\\Desktop\\12619527
201193 OPT 2 COLORBOARD-Cell2.svg";
File file = new File(fileName);
String uri = file.toURI().toString();
ByteArrayOutputStream output = new ByteArrayOutputStream();
org.apache.fop.svg.PDFTranscoder pdf = new org.apache.fop.svg.PDFTranscoder();
TranscoderInput from = new TranscoderInput(uri);
TranscoderOutput to = new TranscoderOutput(output);
pdf.transcode(from, to);
byte[] buffer = output.toByteArray();

is run with 4GB max heap size and generates this stack trace:
