For jstack - it is as published above.

Yes, jmap is as above for me too.

It's very odd.  I can't seem to replicate this on a local build, only with the system install so far.

Hate to nag - but any updates on this? We planned to release jmap and jstack scripts in ovirt 3.3.

Hi Lukas,

Concerning dates - I'm not sure. When is 6.5GA?
Concerning Errata - I don't have permission to the errata site. Any other place I can download this version from?

I can't actually replicate this from a local build as I said, only with a system install of 2.4.2.  I'm afraid I won't have any more time to look at this right now as we have a security errata imminent.

This is affecting the latest RHEL 6.4, java-1.7.0-openjdk-1.7.0.25-2.3.10.4.el6_4.x86_64, and Fedora 19, java-1.7.0-openjdk-1.7.0.60-2.4.2.7.fc19.x86_64, packages as well.

I could reproduce it on RHEL6.4 and F19, both 64-bits, when trying to take a heap dump of JBoss EAP.

I could not find any reference to this issue on KCS, Google and OpenJDK bug reporting system. The closest reference I could find was JDK-6966967.

I tried debugging, but it's way above my technical knowledge, the only think I could find is that it refer to collecting the live regions.

This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.

looks like still the same with java-1.7.0-openjdk-1.7.0.45-2.4.3.4.el6_5.x86_64

Sorry, I did not mean to unset needinfo, only adding myself to CC.

report of similar issue on OpenJDK Runtime Environment (IcedTea6 1.13.1) (rhel-3.1.13.1.el6_5-x86_64)

Is a new bugzilla required for 1.6?

It's very odd that no-one mentioned the workaround.

jmap and jstack need debuginfo.  Install the -debuginfo openjdk package and it should work.

Cheers Andrew. I can confirm this worked for me.

This was not addressed in 1.7.0_55? I've not been able to replicate the issue after having upgraded.

So is this issue reproducible any more?

I can confirm this still occurs with the latest versions of OpenJDK 7, and it still poses a problem.

On an Openshift Enterprise instance, I can see this when using JMap on a JBoss process, which SSH'd into the gear.

Running java -version reports version:
java version "1.7.0_71"
OpenJDK Runtime Environment (rhel-2.5.3.1.el6-x86_64 u71-b14)
OpenJDK 64-Bit Server VM (build 24.65-b04, mixed mode)


This is also reproducible on my dev laptop, running Fedora 20, testing JBoss   or IntelliJ IDEA process. 

RPM -qa reports the package is:
java-1.7.0-openjdk-1.7.0.71-2.5.3.0.fc20.x86_64.


In both cases, the error is the same:

Unfortunately, for the OSE instances, installing the OpenJDK debuginfo package is probably not an option.

Development Management has reviewed and declined this request.
You may appeal this decision by reopening this request.

QAcking, but we do not have any nice test around

Clearing need-info as this is going to get fixed anyway.

(In reply to jiri vanek from comment #35)
> QAcking, but we do not have any nice test around

The test should be similar to the detailed NMT issue. Except for this test debuginfo *must not* be installed:

$ cat ~/HelloWait.java 
public class HelloWait {

    public static void main(String[] args) {
        System.out.println("Hello World");
        try {
            while (true) {
                Thread.sleep(200);
            }
        } catch (InterruptedException e) {
            // ignore
        }
    }

}
$ javac HelloWait.java
$ java HelloWait &
$ sleep 1 && jstack -F $(jps | grep HelloWait | cut -d' ' -f1) > jstack.out 2>&1
$ grep InvocationTargetException jstack.out && echo FAIL
$ jmap -dump:file=hellowait.hprof -F $(jps | grep HelloWait | cut -d' ' -f1) > jmap.out 2>&1
$ grep InvocationTargetException jmap.out && echo FAIL

I see. Thanx!
