Example 21 with ValidationEventHandler

use of javax.xml.bind.ValidationEventHandler in project beam by apache.

the class XmlSourceTest method testReadXMLInvalidRecordClassWithCustomEventHandler.

@Test

    exception.expect(RuntimeException.class);
    // JAXB internationalizes the error message. So this is all we can match for.
