Question

我使用多个SimpleMessageListenerContainers，它们都使用SingleConnectionFactory中的SAME连接。它们都在SingleConnectionFactory的AggregatedExceptionListener中注册。因为，当SingleConnectionFactory的JMS连接断开连接时，需要通知所有SMLC以清除其会话和消费者，并从SCF获取新连接。

但是，当SingleConnectionFactory的AggregatedExceptionListener迭代其“this.delegates”并尝试调用“listener.onException（）”（例如，我的所有SMLC都是委托）时，会发生此错误。

这似乎是Spring类中的一个错误。它应该是，创建委托的副本然后迭代复制的列表，因此如果列表被修改，它不会引发ConcurrentModificationException。

对工作的任何想法都表示赞赏。

这是您怀疑的错误，请参阅https://jira.spring.io/browse/SPR-13421。

应该在即将于2015年10月15日发布的4.1.8和4.2.2版中修复。
