JAXB exception messages: how to change the language?

While validating XML in an XSD file using JAXB, I get JAXBExceptions

in case of invalid XML files. I am getting an exception message by calling event.getMessage()

. The resulting string is in German.

I am using JAXB 2.2. with java 8 on german system.

What determines the language of JAXB exception messages and how can I change it to English?

Here's the code:

SchemaFactory schemaFactory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
try {
    Schema schema = schemaFactory.newSchema();
    JAXBContext jaxbContext = JAXBContext.newInstance("myPackage");
    Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
    unmarshaller.setEventHandler(new XMLValidationEventHandler());
    unmarshaller.setSchema(schema);
    myClass = (myClass) unmarshaller.unmarshal(new File("myFile.xml"));

} catch (SAXException saxE) {
    System.out.println("SAX-Exception during creation of Schema object!");
    saxE.printStackTrace();
} catch (JAXBException e) {}

      

        
        
        
      

    

And this is the event handler:

public class XMLValidationEventHandler implements ValidationEventHandler {

@Override
public boolean handleEvent(ValidationEvent event) {
    System.out.println("XML validation failure in line " 
                       + event.getLocator().getLineNumber() 
                       + ", column " + event.getLocator().getColumnNumber() 
                       + ": " + event.getMessage());
    return true;
}

      

        
        
        
      

    

Below is an example of event handler output:

XML validation failure in line 8, column 48: cvc-maxInclusive-valid: Wert "10000" ist nicht Facet-gültig in Bezug auf maxInclusive "8.0E3" für Typ "Type".
XML validation failure in line 17, column 64: Ungültiger Wert 250 für Feld Day.
XML validation failure in line 17, column 64: cvc-datatype-valid.1.2.1: "2014-02-2501: 00: 00Z" ist kein gültiger Wert für "dateTime".
