SBT ManagedBean property credentialStore is ignored with SmartCloudOAuth2Endpoint

Question

Is seems that the credentialStore property is not being picked up when using the SBT. We have this property:

 <managed-property>
    <property-name>credentialStore</property-name>
    <value>CredStoreCloudant</value>
    </managed-property>

There is no change when I change the value to any odd name, while this name is clearly defined in the managed-beans.xml, like this :

<managed-bean>
        <managed-bean-name>CredStoreCloudant</managed-bean-name>
        <managed-bean-class>com.eoffice.sbt.credentialstore.CloudantCredentialStore</managed-bean-class>
        <managed-bean-scope>application</managed-bean-scope>
    </managed-bean>

The managed-beans.xml is being used, when we change the property clientID , we do get the 401 error:

oauth_invalid_clientid

Which is expected behaviour. The OAuth dance is performed nicely, but our code does not execute. It appears to be using the MemoryStore.
