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

Question

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.

This can be either a bug in HotSpot Serviceability Agent or an attempt to get a stacktrace while JVM is in inconsistent state. In both cases you can hardly do anything about it. — apangin, Jul 14 '18 at 23:05
Why do you want `-m` mode? If you are interested in non-Java stack, then `gdb` should be a better tool for this. — apangin, Jul 14 '18 at 23:06
I'm observing long running requests in a web application. Threaddumps point at native classloading methods. My question in https://stackoverflow.com/questions/49507981/unsafe-defineclass-hangs-slow-reflection-calls lead to this tooling issue. — chrempl, Jul 16 '18 at 04:28

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.

Exactly the same issue: jstack without the mixed mode flag is running fine. But i'm using Oracle jdk 1.8.0_172. – chrempl Jul 13 '18 at 05:11

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.

Thank you for the hint. I'm using the jstack of the jvm which runs the process. – chrempl Jul 12 '18 at 12:52

I had the same problem when using HSDB on openjdk-8. Installing lib sudo apt-get install openjdk-8-dbg works.
