[rules-users] NPE loading Drools 5.4.0.Beta1 using drools-spring

[lhorton]

I am trying to load up 5.4.0.Beta1.  I'm using Spring configuration xml that
works fine in 5.2.0.Final.  In the xml, my grid-node is defined as:

<drools:grid-node id="droolsClusterNode1"/>

The exception is a NPE on a method in WhitePagesClient.  Any idea what the
cause might be?  Has anyone successfully loaded 5.4.0 using Spring?

The full exception is:

ERROR 2012-01-06 15:51:05,998
[org.springframework.web.context.ContextLoader] - Context initialization

org.springframework.beans.factory.BeanCreationException: Error creating bean
