Exception in thread "Transport Thread" java.lang.AbstractMethodError: org.apache.xerces.dom.DeferredDocumentImpl.getXmlStandalone()Z

I'm trying to add Hazelcast to an existing project and I'm seeing this exception:

Oct 3, 2012 3:33:39 PM com.hazelcast.config.XmlConfigBuilder
WARNING: Could not find hazelcast.xml in classpath.

Typically I can run a simple Hazelcast application without specifying a configuration file. I found a thread via Google that says this problem is caused by an older version of xerces that must be getting included from another dependancy - I'm using Hibernate & Hibernate Spatial among others. But how do I override the version of Xerces used?

Thanks
