Exception when configuring JPA Identity Store via PicketLink subsystem

When configuring the PicketLink subsystem with a JPA-based IdentityStore, I get the following exception on app server startup:

The subsystem configuration looks like this:

<subsystem xmlns="urn:jboss:domain:picketlink:1.0">
<identity-management jndi-name="picketlink/JPADSBasedPartitionManager" alias="jpa.ds.based.partition.manager">
<identity-configuration name="jpa.config">
<jpa-store data-source="jboss/datasources/PicketLinkDatasource">
<supportedTypes supportsAll="true"/>
</jpa-store>
</identity-configuration>
</identity-management>
</subsystem>

This config worked under 2.6.0.Beta3, but fails under 2.6.0.CR1
