jmap, jstack not working properly with OpenJDK

I run into an issue lately with the jmap and jstack implementation of OpenJDK. Quite frankly – they didn’t work…
When running jmap -heap, I would get:

Exception in thread "main" java.lang.reflect.InvocationTargetException

When running jstack -F I would get:

Can't print deadlocks:Unable to deduce type of thread from address 0x00007fc980001000 (expected type JavaThread, CompilerThread, ServiceThread, JvmtiAgentThread, or SurrogateLockerThread)

The fix was simple (as some dear guys in the OpenJDK explained to me). Make sure you install openjdk-debuginfo package. That should fix it.

  1. I ran into the same problem (RHEL 6, JBoss EAP 6.2). How did you install that package? I tried yum install java-1.7.0-openjdk-debuginfo but it says that it can’t find the package.

    Thanks for your advice

    1. I know it’s late, probably other people will find it useful.
      This package can be installed with command:
      debuginfo-install java-1.7.0-openjdk
