我正在尝试以混合模式在 ubuntu 上运行 jstack:
$ jstack -m 7219
结果是这个异常:
Attaching to process ID 7219, please wait...

PID 为 7219 的进程由与 jstack 相同的用户启动。
最佳答案
我在 Ubuntu 上遇到了同样的问题，安装了 openjdk-9-jdk-headless，单独使用 jstack 就可以正常工作，但是 jstack -m 会失败并出现与您相同的错误。
安装 openjdk-9-dbg(带有调试符号的包)解决了这个问题。
关于java - 混合模式下的 jstack : WrongTypeException: No suitable match for type of address，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/49516601/
