Java Spring wired EhCache磁盘存储在多线程应用程序中创建冲突

直觉：看起来有点像两个线程都试图初始化基于磁盘的溢出缓存，但其中一个失败了

此应用程序中有两个线程。在以下日志提取中，它们由id0000004a和0000003d表示。它们同时开始：

[3/04/12 10:17:50:832 EST] 0000004a EhCacheManage I org.springframework.cache.ehcache.EhCacheManagerFactoryBean afterPropertiesSet Initializing EHCache CacheManager
[3/04/12 10:17:50:832 EST] 0000003d EhCacheManage I org.springframework.cache.ehcache.EhCacheManagerFactoryBean afterPropertiesSet Initializing EHCache CacheManager

EhCache通过Spring连接：

<ehcache:annotation-driven cache-manager="ehCacheManager"/>
<bean id="ehCacheManager" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"/>

并据此配置：

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd" updateCheck="false">
    <diskStore path="java.io.tmpdir/GMM_DAO_Caches"/>

    <defaultCache eternal="false" maxElementsInMemory="1000"
              overflowToDisk="false" diskPersistent="false" timeToIdleSeconds="0"
              timeToLiveSeconds="300" memoryStoreEvictionPolicy="LRU"/>

    <cache name="dao_results" eternal="false" maxElementsInMemory="1000"
           overflowToDisk="true" diskPersistent="false" 
           timeToIdleSeconds="0" timeToLiveSeconds="3600"
           memoryStoreEvictionPolicy="LRU"/>

    <cache name="dao_results_shortlived" eternal="false" maxElementsInMemory="1000"
           overflowToDisk="true" diskPersistent="false" 
           timeToIdleSeconds="0" timeToLiveSeconds="300"
           memoryStoreEvictionPolicy="LRU"/>

</ehcache>
