JBoss 6.0.0.M2

I get following stack trace when I click "type=HotSpotDiagnostic" link in jmx-console. Is this a known issue/bug?

14:44:24,944 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/jmx-console].[jsp]] Servlet.service() for servlet jsp threw exception: java.lang.NullPointerException
