jstack in mixed mode: WrongTypeException: No suitable match for type of address

问题

I'm trying to run jstack on ubuntu in mixed mode:

 $ jstack -m 7219

The result is this exception:

The process with PID 7219 was started with the same user as jstack.

回答1:

I've had the same issue on Ubuntu, with openjdk-9-jdk-headless installed, jstack alone would work fine but jstack -m would fail with same error as you.

Installing openjdk-9-dbg (package that brings debug symbols) solved it.

回答2:

The same user is fine, but make also sure you are using the jstack that is bundled the exact same JVM as the one that is running the process 7219.
