  The method

public Schema newSchema(File schema) throws SAXException

in the class javax.xml.validation.SchemaFactory does not detect
violation of the constraints described in XML Schema spec (XML Schema Part 1: Structures,
Section 3.9.6 Constraints on Particle Schema Components, Schema Component Constraint:
Particle Valid (Restriction) ).

New 188 JCK-15 beta2 tests adopted from W3C XSTC-20020116 testsuite (see the list below)
check that the validator detects the Particle Valid Restriction constraints, such as

Occurrence Range OK,
Particle Restriction OK (Elt:Elt -- NameAndTypeOK),
Particle Derivation OK (Elt:Any -- NSCompat),
Particle Derivation OK (Elt:All/Choice/Sequence -- RecurseAsIfGroup)
...

All the tests fail since the test schemas are accepted as valid ones.

The bug is found in jdk1.5.0/beta/b35 and it is reproducible in jdk1.5.0/beta/b36.

Similar bug was reported a year ago against JAXP 1.2. For more details see
4793367 invalid particle restriction is not detected

To reproduce the bug compile and run the following code as shown in the log below.
Instead of the test.xsd try different schemas from the mentioned tests
that violate various parts of the Particle Valid Restriction constraint:
------------------------------------------ test.java
import java.io.File;
import org.xml.sax.SAXException;
import org.xml.sax.SAXParseException;
import org.xml.sax.helpers.DefaultHandler;
import javax.xml.validation.SchemaFactory;

public class test {

    protected static class ErrorHandler extends DefaultHandler {
        public int errorCounter = 0;

        public void error(SAXParseException e) throws SAXException {
            System.out.println(e);
            errorCounter++;
        }

        public void fatalError(SAXParseException e) throws SAXException {
            System.out.println(e);
            errorCounter++;
        }
    }

    public static void main(String [] args) {
        SchemaFactory schemaFactory =
                SchemaFactory.newInstance("http://www.w3.org/2001/XMLSchema");

        ErrorHandler errorHandler = new ErrorHandler();
        schemaFactory.setErrorHandler(errorHandler);

        try {
            schemaFactory.newSchema(new File(args[0]));
        } catch (SAXException e) {
            exit(1, "Fatal Error: " + e);
        }

        if (errorHandler.errorCounter == 0) {
            exit(1, "Failed: " + args[0] + " is valid");
        } else {
            exit(0, "Passed.");
        }
    }

    public static void exit(int errCode, String msg) {
        System.out.println(msg);
        System.exit(errCode);
    }
}
----------------------------------------------------

Restriction OK (Elt:Elt -- NameAndTypeOK).
