EHCache报出java.lang.IllegalMonitorStateException异常

我写的代码如下所示，其中EHCacheService.putIn是封装了EHCache的put函数，key=1，一直key++。
import java.util.concurrent.Callable;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.Future;

public class EHCacheTestCallable implements Callable {

@Override
public Object call() throws Exception {
    //for (int i = 0; i < thresd; i++) {
    for (int i = 0; ; i++) {
        EHCacheService.putIn("aba");
    }
}

public static void main(String[] args) {
    EHCacheTestCallable psc = new EHCacheTestCallable();
    ExecutorService es = Executors.newFixedThreadPool(1);
    @SuppressWarnings({ "unchecked", "unused" })
    Future recvHandler = es.submit(psc);
}

}
另外ehcache.xml中配置为：
maxElementsInMemory="10000"
eternal="false"
timeToIdleSeconds="300"
timeToLiveSeconds="600"
overflowToDisk="true"
/>
存储的内容为一个字符串“aba”，存到2138639个的时候出现异常。
异常结果显示为：
