Single Spring based ehcache manager for multiple ehcache.xml files in a multi module project

I have a multi module project with all the modules defining their cache configurations in their own ehcache.xml. This use case is addressed by the now unmaintained "ehcache-spring-annotations" project through a configuration like this:

    <ehcache:annotation-driven cache-manager="ehCacheManager" create-missing-caches="true"/>

    <bean id="ehCacheManager" class="net.sf.itcb.addons.cachemanager.ItcbEhCacheManagerFactoryBean">
      <property name="configLocations" value="classpath*:ehcache.xml"/>
      <property name="shared" value="true"/>
    </bean>

I tried something similar in Spring's Cache Abstraction.

    <cache:annotation-driven/>

    <bean id="cacheManager"
      class="org.springframework.cache.ehcache.EhCacheCacheManager" 
      p:cache-manager-ref="ehcache"/>

    <bean id="ehcache"
      class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"      
      p:config-location="classpath*:ehcache.xml"/>

However, I ran into this exception:

Caused by: java.io.FileNotFoundException: 
  class path resource [classpath*:ehcache.xml] cannot be opened because
  it does not exist

Can someone please explain what is the correct way to configure Spring's Cache Abstraction for EhCache in a multi module project?

In the end, we moved away from ehcache.xml and started using Java based configuration for our caches which solved this problem.
