Summary: DOM4J 1.6.1 xml file generation Exception
Initial Comment:
I use DOM4J 1.6.1 to write a custom build domcument to
an XML file.
It fails with a StringIndexOutOfBoundsException.
If I do the same with DOM4J 1.5.1 I have no problem.
My tree contains a lot of empty elements and use
sometimes stange names (characters like +,-,_)
Here is the code I use to write the XML file:
OutputFormat outformat =
OutputFormat.createPrettyPrint();
document.getRootElement().normalize();
try{
((VFSXmlFileObject)this.getRoot()).flushChilds();
XMLWriter writer = new
XMLWriter(this.getParentLayer().getContent().getOutputStream(false),
outformat);
writer.write(this.document);
writer.flush();
writer.close();
document = null;
}catch (Exception e){
e.printStackTrace();
}
Here is the Exception:
java.lang.StringIndexOutOfBoundsException: String index
out of range: 0
[java] at java.lang.String.charAt(String.java:558)

I have a simpler code to reproduce this bug. Its still there:
import java.io.FileWriter;
import java.io.IOException;
import org.dom4j.Document;
import org.dom4j.DocumentFactory;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;
import org.dom4j.io.OutputFormat;
import org.dom4j.io.XMLWriter;
public class Dom4jBug {
public static void main(String[] args) {
try {
Document doc = DocumentHelper.createDocument();
Element rootElem = doc.addElement("root");
Element propElem =
DocumentFactory.getInstance().createElement("property");
propElem.addElement("item");
propElem.setText("");
rootElem.add(propElem);
OutputFormat format = OutputFormat.createPrettyPrint();
XMLWriter writer = new XMLWriter(new FileWriter("test.xml"),
format);
writer.write(doc); // <== throws
StringIndexOutOfBoundsException !!!
writer.close();
} catch (IOException ex) {
ex.printStackTrace();
}
}
}
