Hi,

not sure to be on the right ML to report this behavior, please help me
to find the right place to do it if not... and sorry for the noise.

I use gcj on a LTS Ubuntu:
gcj (Ubuntu 4.4.1-5ubuntu2) 4.4.1

My sample code may be downloaded here as Test.java:
https://bugzilla.wikimedia.org/attachment.cgi?id=7115

and looks like that:
================================
import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;
import org.xml.sax.helpers.DefaultHandler;

public class Test {

    public static void main(String argv[]) {

	try {

	    SAXParserFactory factory = SAXParserFactory.newInstance();
	    SAXParser saxParser = factory.newSAXParser();

	    DefaultHandler handler = new DefaultHandler() {};
 	    saxParser.parse("test.xml", handler);

	} catch (Exception e) {
	    e.printStackTrace();
	}
    }
}
================================

I compile it like following:
gcj -o test --main=Test Test.java

My XML file "test.xml" may be downloaded here:
https://bugzilla.wikimedia.org/attachment.cgi?id=7114

By running the the binary I get the following error:
$ ./test

   at javax.xml.parsers.SAXParser.parse(libgcj.so.10)
   at Test.main(test)

   at gnu.xml.stream.XMLParser.next(libgcj.so.10)
   at gnu.xml.stream.SAXParser.parse(libgcj.so.10)
   ...3 more

Although the XML should be valid.

Has someone an idea to explain this behavior?
