从 Websphere 使用 Elasticsearch Java 客户端时出错

Question

我有一个使用 elasticsearch 官方 java 客户端的 Web 应用程序。使用 IBM JVM Java 7 在 Websphere 8.5.5 上使用该 Web 应用程序时，出现以下错误。我尝试使用传输客户端和节点客户端。还尝试使用 Oracle JavaSE 7 和 8 作为 Elasticsearch 的 JVM。但没有任何结果。 Elasticsearch 在 IBM JVM 上没有运行，Websphere 在 IBM JVM 上只有运行。

有人知道从 Websphere 上的应用程序使用 elasticsearch 官方 java 客户端的方法吗？

下面是错误堆栈跟踪：

此问题的唯一解决方法是对两个 Java 应用程序使用相同的 JVM。 Java 异常的序列化在使用不同更新版本的相同 JVM 之间可能不一致，显然这是 IBM 的 JVM 和你的运行 Elasticsearch 之间的问题.

具体来说，Elasticsearch 不在 IBM JVM 上运行因为 IBM JVM has bugs in it that prevent it from working correctly.

幸运的是这里的前景好多了。 IBM is working with Elasticsearch to get it working properly and Elasticsearch is removing serialization in Elasticsearch 2.0.
