Java JIT编译失败（IBM JVM）

我在WebSphere7.0上运行我的web应用程序。它工作了一段时间，但JVM崩溃并生成核心转储。 从javacore***文件：

似乎JVM在数组的JIT编译期间崩溃了。sort（）方法。我不知道为什么会这样。我尝试了-Xjit:exclude{…}，它解决了这个问题，但在本例中，我对性能不满意

我责怪IBM的JVM中的Arrays.sort（），并以与Oracle的JVM（复制粘贴代码）中完全相同的方式实现了我自己的排序，并且暂时忘记了这个问题。但昨天JVM在同一任务中再次崩溃。新javacore文件中唯一的区别是

1XHEXCPMODULE  Compiling method: com/sort/util/SortUtils.sort([JII)V

其中SortUtils.sort是我的新实现

请解释一下，这是JIT康普利勒的错误还是我做错了什么？有没有关于如何修复的建议？这可能是硬件相关的问题吗？

这肯定是一个JVM错误。您的代码以与JDK相同的方式失败也是意料之中的：JIT编译器即将对其执行相同的编译。或者您可以使用另一个JVM？
