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
org.xml.sax.SAXParseException: not a name start character: "U+26"

at javax.xml.parsers.SAXParser.parse(libgcj.so.10)
at javax.xml.parsers.SAXParser.parse(libgcj.so.10)
at Test.main(test)
Caused by: javax.xml.stream.XMLStreamException: not a name start

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?
This "bug" impacts the Mediawiki mwdumper SW. T
