Compile and run the following program, a bare-bones usage of XSLT transforms:

---%<---
import java.io.StringReader;
import java.util.Locale;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.transform.Source;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.stream.StreamSource;
import org.w3c.dom.Document;
public class TestTurkishXSLT {
    public static void main(String[] args) throws Exception {
        Locale.setDefault(new Locale("tr", "TR"));
        String xslt =
            "<xsl:stylesheet version='1.0' xmlns:xsl='http://www.w3.org/1999/XSL/Transform&#39;>\n" +
            " <xsl:output method='xml' indent='yes' omit-xml-declaration='yes'/>\n" +
            " <xsl:template match='/'>\n" +
            " <hello/>\n" +
            " </xsl:template>\n" +
            "</xsl:stylesheet>";
        Source source = new StreamSource(new StringReader(xslt));
        Transformer t = TransformerFactory.newInstance().newTransformer(source);
        Document doc = DocumentBuilderFactory.newInstance().newDocumentBuilder().getDOMImplementation().createDocument(null, "x", null);
        t.transform(new DOMSource(doc), new StreamResult(System.out));
    }
}

Results under JDK 1.4.2 are as expected:

---%<---
$ /space/jdk1.4/bin/java -showversion -cp /tmp/test-turkish-xslt/build/classes TestTurkishXSLT
java version "1.4.2_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_06-b03)
Java HotSpot(TM) Client VM (build 1.4.2_06-b03, mixed mode)

<hello/>
---%<---

However under JDK 1.5 (or later), it is broken:

---%<---
$ /space/jdk1.5/bin/java -showversion -cp /tmp/test-turkish-xslt/build/classes TestTurkishXSLT
java version "1.5.0_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_01-b08)
Java HotSpot(TM) Client VM (build 1.5.0_01-b08, mixed mode)

Here <<<DOTLESS-i>>> is the Turkish lowercase dotless 'i'.

Removing the call to Locale.setDefault, or using e.g. fr_FR, does not exhibit any bug; only Turkish locale.
