WildFly 8.2 中的计时器恢复错误

Question

从 JBoss 5.1 升级到 WildFly 8.2 后，我收到了下一个错误日志。同时 - 一切正常。

Caused by: an exception which occurred:
in field trId
in object of type com.......StorageData
in element at index [1] of size [4]
in field second
in object of type com.......Pair
in field info
in object of type org.jboss.as.ejb3.timerservice.persistence.TimerEntity

Pair - 包含两个值（Serializable）

StorageData - 一些数据（Serializable），包括 Long trId 字段

在 bean 中：

@Resource
private TimerService service;

protected void startAsync(Integer id, Object... params) {
    service.createTimer(0, new Pair<Integer, Object[]>(id, params));
}

如何消除此错误？

Answer 1

我的 JBoss EAP 6.4.6 也有同样的问题。 我发现 Timer Service 缓存在 JBoss 数据目录中。 我只需要删除 timer-service-data 文件夹中的所有文件夹。

Answer 2

发现问题 - 对象中的最后一个参数...参数不是可序列化的。
