[Opensymphony-oscache] why i can still get the cached object after flushEntry(key) is called?

Hi,
    I am using OSCache in my project, and recently we have found a problem, in order to demonstrate the problem, i have wrote a small test program:

package cache.test;

import com.opensymphony.oscache.base.CacheEntry;
import com.opensymphony.oscache.general.GeneralCacheAdministrator;

public class TestOSCache {

    public static void main(String[] args) throws Exception {
        GeneralCacheAdministrator cache = new GeneralCacheAdministrator();
        cache.putInCache("0", "0");
        cache.putInCache("1", "1");
        cache.putInCache("2", "2");
        cache.putInCache("3", "3");
        cache.putInCache("4", "4");
        cache.putInCache("5", "5");
        cache.putInCache("6", "6");
        cache.putInCache("7", "7");
        cache.putInCache("8", "8");
        cache.putInCache("9", "9");
        cache.flushEntry("1");
        try {
            System.out.println("a" + cache.getCache().getFromCache("1", CacheEntry.INDEFINITE_EXPIRY));
        }catch (Exception e) {
            e.printStackTrace(System.out);
        }
        try {
            System.out.println("b" + cache.getFromCache("1", CacheEntry.INDEFINITE_EXPIRY));
        } catch (Exception e) {
            e.printStackTrace(System.out);
        }
    }
}

the result is:
2005-05-18 17:20:32,584 Properties {cache.algorithm=com.opensymphony.oscache.base.algorithm.UnlimitedCache, cache.capacity=1000000, cache.memory=true}
2005-05-18 17:20:32,584 Constructed GeneralCacheAdministrator()

b1

    our problem is why we can still get the object at point b after cache.flushEntry("1") has been called?

    Thanks!
