大约每2-3-4周，我必须重新开始我们的开发，有时还会测试WAS服务器，因为它得到OutOfMemoryError。在WAS实例上只安装了一个使用spring / hibernate的应用程序。在通过jython脚本安装新版本的应用程序时，总会发生OutOfMemoryError。它好像20次，然后它得到一个OutOfMemoryError。我已经将最大堆大小增加到1GB，但唯一的结果是，在内存已满之前需要更多时间（或应用程序安装）。 用堆分析器查看转储，我发现以下泄漏可疑：

很遗憾，我还没有找到任何关于WebAppConfigurationImpl的帮助。你们有没有经历过类似的问题？既然它是ibm软件包的一部分，我应该把它作为潜在的bug报告给IBM吗？
