   The method

public Schema newSchema(File schema)

in the class javax.xml.validation.SchemaFactory throws
java.util.MissingResourceException which is not an instance of SAXException.

According to the javadoc, the method is allowed to throw SAXException or
NullPointerException. So it is an error to throw MissingResourceException.

The bug affects the following new JCK-15 beta2 test adopted from W3C XSTC-20020116 testsuite:
     api/xml_schema/msxsdtest/identityConstraint/idJ002.html#idJ002

The bug is found in jdk1.5.0/beta/b41 and it is not reproducible with jdk1.5.0/beta/b40.

To reproduce the bug compile and run the following code as shown in the log below.
