如何获取Java.exe/jvm.dll的符号文件以分析崩溃核心转储文件？

我有一个Java应用程序在Websphere应用程序服务器上运行。当我分析系统崩溃核心转储文件时，我得到如下信息：

ERROR: Symbol file could not be found.  Defaulted to export symbols for J9THR23.dll 

如何获取Java的符号文件

提前谢谢

详情如下：

看起来调试器正在查找PDB文件，据我所知，java应用程序的调试信息不是PDB文件。PDB文件是在创建Windows本机应用程序时由VisualStudio生成的，因此调试器似乎在寻找应用程序服务器的调试符号。不知道WebSphere是否有自己的调试版本。另一方面，如果您想为java应用程序调试符号，只需使用

-g

选项重新编译即可。

它包括.pdb文件

我从不查看来自websphere的转储文件。通常，应用程序日志包含确定java应用程序失败原因所需的所有信息。您在寻找什么？我相信这里提供的文件不是真正的PDB文件，而是Java二进制文件的完整构建，具有不同的编译选项，其中碰巧包括PDB文件。但这些都无助于查看生产JVM中的现有转储。
