Hi all,
I'm having troubles running an xml schema validation unit test from
Gradle. It's a relatively simple test, but it uses some XML Schema 1.1
features in the XSD. These features seem to really react badly to
running in a Gradle worker process. Running exactly the same code from
Ant has no problems, but when running from Gradle, I get an error with
a stack trace pointing to some problem deep in the XML processing
libraries. Can anyone help with suggestions on how to avoid this, or
fix the root cause?
I have packaged up a small example which demonstrates this problem.
There are 2 tests in the class. Both should pass, but when running
from gradle, the first test fails with the following stack trace
(which I have put below)
Here's the test:
SchemaValidationTest.java:

public class SchemaValidationTest {
@Test
public void validateSchemaSimple() throws Exception {
StreamSource schemaDocument = new
StreamSource(getClass().getResourceAsStream("simpleWithAssert.xsd"));
Source instanceDocument = new
StreamSource(getClass().getResourceAsStream("simpleTest.xml"));
validate(schemaDocument, instanceDocument);
}
@Test
public void validateSchemaWithoutOnePointOneFeatures() throws Exception {
StreamSource schemaDocument = new
StreamSource(getClass().getResourceAsStream("simpleWithoutAssert.xsd"));
Source instanceDocument = new
StreamSource(getClass().getResourceAsStream("simpleTest.xml"));
validate(schemaDocument, instanceDocument);
}
private void validate(StreamSource schemaDocument,
Source instanceDocument) throws SAXException,
IOException {
SchemaFactory schemaFactory =
SchemaFactory.newInstance("http://www.w3.org/XML/XMLSchema/v1.1";);
Schema schema = schemaFactory.newSchema(schemaDocument);
Validator validator = schema.newValidator();
validator.validate(instanceDocument);
}
}

========================
I have all this code, build scripts, and library jars packed up in a
zip file. It was 2.5MB includes jars, and I didn't want to post that
to the mailing list. If anyone wants to have a look, let me know and
I'll send you the zip.
Thanks,
Joe
