類未找到在集羣環境中的openfire中的Hazelcast插件中的異常

我已經在3 EC2實例中安裝了openfire，並在所有三個實例中添加了hazelcast插件。所有三個節點都正常工作。但有一段時間，我在stderror日誌中得到這個異常，請幫助我確定爲什麼會發生此異常，並且如何避免此錯誤日誌？？？類未找到在集羣環境中的openfire中的Hazelcast插件中的異常

看來你必須在你的Hazelcast集羣中部署一些openfire jar。 Hazelcast由於安全原因不提供遠程類加載（否則每個人都可以注入一切）。

你能否具體說明我需要將哪個jar添加到hazelcast插件jar中，以及我必須添加哪個位置？ – udhaya

節點不知道，但我會猜想openfire.jar？ – noctarius

我重新啓動了所有3個節點，發現這個異常發生在2.30小時之後，並且每秒拋出一次。這與垃圾收集器有關嗎？是否因爲clusteredcachefactory類被垃圾收集，這就是發生這種異常的原因？ – udhaya
