OO 2.1 with jre 1.6 - xml validation problem

Hi,

i have a problem with one of my oo java extensions using jre 1.6. 
the extensions gets a xml string from a database, validates against
a schema and insert parts of the xml string into an oo writer document...

there is no problem if i use jre 1.5 instead or if i run the program *without* 
oo (standalone) ... even jre 1.6 with oo 2.0.4 worked perfect ...

the code seems to crash at "Schema schema = factory.newSchema(schemaFile)".
here is the class:

public class XMLSchemaValidator {

    private SchemaFactory factory = SchemaFactory
            .newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);

    private Node node = null;
    private Reader schema = null;

    public XMLSchemaValidator(Node doc, Reader schema) {
        this.node = doc;
        this.schema = schema;
    }

    public XMLSchemaValidator(Node doc, String schema, String encoding) {
        this.node = doc;
        this.schema = new XReader().getReaderFromFile(schema, encoding);
    }

    public synchronized void validate() throws SAXException, IOException {

        if (node == null || schema == null)
            return;

        Source schemaFile = new StreamSource(schema);
crash-> Schema schema = factory.newSchema(schemaFile);
        Validator validator = schema.newValidator();
        validator.validate(new DOMSource(node));
    }
}

my remote debugger generates the following error message and jumps to the
EventDispatchThread class ...

Thread AWT-EventQueue-0 Suspended(noSuch Method Error)
          Event-DispatchThread.run()  line 155

line 155 is empty :-) ...

  void pumpEventsForHierarchy(Conditional cond, Component modalComponent) {
      pumpEventsForHierarchy(ANY_EVENT, cond, modalComponent);
  }

  [155 -> empty line]

  void pumpEvents(int id, Conditional cond) {
      pumpEventsForHierarchy(id, cond, null);
