我正在使用具有磁盘存储持久性的缓存。在随后重新运行该应用程序时，出现以下错误：

net.sf.ehcache.store.DiskStore deleteIndexIfCorrupt
WARNING: The index for data file MyCache.data is out of date,
probably due to an unclean shutdown. Deleting index file MYCache.index

除了net.sf.ehcache.CacheManager.shutdown()在应用程序中的某个位置显式调用之外，还有什么方法可以解决此问题？

缓存配置：

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:noNamespaceSchemaLocation="ehcache.xsd"
             updateCheck="true" monitoring="autodetect">

    <diskStore path="C:\work"/>

    <cacheManagerEventListenerFactory class="" properties=""/>

    <cacheManagerPeerProviderFactory
            class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"
            properties="peerDiscovery=automatic,
                        multicastGroupAddress=230.0.0.1,
                        multicastGroupPort=4446, timeToLive=1"
            propertySeparator=","
            />

    <cacheManagerPeerListenerFactory
            class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"/>

    <defaultCache
            maxElementsInMemory="1"
            eternal="false"
            timeToIdleSeconds="0"
            timeToLiveSeconds="86400"
            overflowToDisk="true"
            diskSpoolBufferSizeMB="1"
            maxElementsOnDisk="10000"
            diskPersistent="true"
            diskExpiryThreadIntervalSeconds="120"
            memoryStoreEvictionPolicy="LFU"
            />

</ehcache>

复制问题的代码：

import java.util.ArrayList;
import java.util.List;

import net.sf.ehcache.Cache;
import net.sf.ehcache.CacheManager;
import net.sf.ehcache.Element;

public class CacheTest {
    static CacheManager manager = new CacheManager(CacheTest.class
            .getResource("ehcache.xml"));
    static Cache cache;

    public static void main(String[] args) {

        // Get a default instance
        manager.addCache("test");
        cache = manager.getCache("test");

        // Generate some junk so that the
        // cache properly flushes to disk
        // as cache.flush() is not working
        List<String> t = new ArrayList<String>();
        for (int i = 0; i < 1000; i++)
            t.add(null);
        // Oddly enough fewer elements
        // do not persist to disk or give
        // an error
        for (int i = 0; i < 100000; i++) {
            cache.put(new Element(i, t));
        }
        cache.flush();

        if (cache.get("key1") == null) {
            System.out.println("key1 not found in cache!");
            cache.put(new Element("key1", "value1"));
        }

        System.out.println(cache.get("key1"));
    }
}
