We've found a problem with DS 1.0.2.  This problem only exists when running with DS embedded in the same VM.
Running the same code remotely (outside of DS VM) works fine.
Example code:
            Attributes attrs = new BasicAttributes();
            attrs.put("objectClass", "organizationalUnit");
            attrs.put("description", "Test OU");
            DirContext subContext = context.createSubcontext("ou=Test", attrs);
Exception from createSubcontext():
Caused by: java.lang.NullPointerException

 at org.apache.directory.server.core.schema.SchemaService.assertAllAttributesAllowed(SchemaService.java:1806)

If you change the BasicAttributes() constructor call to:
            Attributes attrs = new BasicAttributes( true );
it works fine.
This issue means we cannot use DS 1.0.2.  Should I raise a JIRA entry yet or should I hold off until you guys have had chance to check my findings?
Many Thanks
