Ehcache Second Level Cache working on JBoss Fuse

Issue

• We ave hit an issue with some second level caches that we had set up with Hibernate and Ehcache.
• On JBoss Fuse, we have installed, spring-jdbc, spring-orm, camel-jpa, jpa-hibernate features.
• When we deploy our application with the following set up in a bundle context as below,

<bean id="rdisAnnotationsSessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">

        <property name="hibernateProperties">
            <util:properties>
                <prop key="hibernate.connection.pool_size">1</prop>
                <prop key="hibernate.show_sql">false</prop>
                <prop key="hibernate.dialect">${hibernate.dialect}</prop>
                <prop key="hibernate.connection.autocommit">true</prop>

                <!-- entity and query caching -->
                <prop key="hibernate.cache.use_structured_entries">true</prop>
                <prop key="hibernate.cache.use_second_level_cache">true</prop>
                <prop key="hibernate.cache.use_query_cache">true</prop>
                <prop key="hibernate.generate_statistic">true</prop>
                <prop key="hibernate.cache.region.factory_class">org.hibernate.cache.ehcache.EhCacheRegionFactory</prop>

            </util:properties>
        </property>

        <property name="namingStrategy" ref="namingStrategy" ></property>
        <property name="dataSource" ref="someDataSource" ></property>
    </bean>

we get the following below exceptions,
