Configurar o EhCache com Hibernate 3.3 e Spring

Galera, estou com problemas ao tentar habilitar um cache do Hibernate 3.3 com o Spring:

<bean id="sessionFactory"
		class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
        <property name="configLocations">
            <list>                
                <value>classpath:/hibernate.cfg.xml</value>
            </list>
        </property>
        
		<property name="hibernateProperties">
			<value>				
				hibernate.dialect=${hibernate.connection.dialeto}
				hibernate.query.substitutions=true 'Y', false 'N'
				
				hibernate.cache.use_second_level_cache=true
				hibernate.cache.use_query_cache=true
				hibernate.cache.region.factory_class=net.sf.ehcache.hibernate.EhCacheRegionFactory
				
				hibernate.connection.lc_ctype=ISO8859_1
				hibernate.show.sql = true
				hibernate.format.sql = true
				
				
			</value>
		</property>
	</bean>
	
	<bean id="transactionManager"
		class="org.springframework.orm.hibernate3.HibernateTransactionManager" >
		<property name="sessionFactory" ref="sessionFactory" />
	</bean>

Coloquei a lib ehcache-core-2.4.2 no classpath

E ao debugar o erro ocorre na linha que chama o cache:

E o arquivo ecache.xml esta criado na raiz do classpath.

E ocorre o seguinte erro:

java.lang.ArrayIndexOutOfBoundsException: 0

Sera que ainda falta alguma dependencia?

Meu ehcache.xml esta assim:

Boa noite Pedrosa,

Você achou a causa raíz desse problema?
