When I try to create a javax.xml.validation.Schema instance off of the Servlet 2.4 deployment descriptor schema ("web-app_2_4.xsd"), I get the exception below.

To reproduce, compile the attached SchemaTester.java, unzip the attached schemas.jar.zip, and invoke this command:

  % java -classpath schemas.jar:. SchemaTester

I'm using jdk1.5.0_06.

Here's the exception I'm getting:

Exception in thread "main" org.xml.sax.SAXParseException: sch-props-correct.2: A schema cannot contain two global components with the same name; this schema contains two occurrences of 'http://java.sun.com/xml/ns/j2ee,descriptionGroup'.
