Performance issue with Xalan transformer and very large text nodes

Code to reproduce: import java.io.ByteArrayInputStream; import javax.xml.transform.Transformer; import javax.xml.transform.TransformerFactory; import javax.xml.transform.TransformerException; import javax.xml.transform.TransformerConfigurationException; import javax.xml.transform.dom.DOMResult; import javax.xml.transform.stream.StreamSource; StringBuilder sb = new StringBuilder(); sb.append( "<thing>" ); while (sb.length() < 50*1024*1024) { //50MB sb.append("iunfgq0irg02i4t985023gwhj9eroisghvpoweisvdj”); //random blob } sb.append( "</thing>" ); TransformerFactory tFactory = TransformerFactory.newInstance(); Transformer transformer = tFactory.newTransformer(); ByteArrayInputStream bais = new ByteArrayInputStream(sb.toString().getBytes()); StreamSource source = new StreamSource(bais); DOMResult result = new DOMResult(); transformer.transform(source, result);
