H2 Datasource fails in domain mode

[Server:server-one] 14:20:07,644 ERROR [org.jboss.as] (MSC service thread 1-3) JBoss AS 7.0.0.Beta2 "(TBD)" started (with errors) in 3449ms - Started 77 of 104 services (2 services failed or missing dependencies, 24 services are passive or on-demand)
[Server:server-one] Services missing dependencies:
[Server:server-one] service jboss.data-source.reference-factory.java:/H2DS
[Server:server-one] service jboss.naming.context.java.java:/H2DS

Partly this is because this is missing from domain.xml:

<drivers>
<driver module="com.h2database.h2"/>
</drivers>

But when I add that the server's don't complete startup (i.e. the server started messages are never logged) and when I ctrl-c stop the process controller, the same messages get logged.

I suspect there is a problem with the DESCRIBE operation handler.
