SIGSEGV caused by compiled Java code

[Reto Merz]

Hello,

We can always reproduce a JVM crash SIGSEGV caused by compiled Java code.
At the moment we can it only reproduce on Linux system (Ubuntu 22.04.3 LTS), and not on Windows.

First we have seen it with version
OpenJDK Runtime Environment Temurin-17.0.4.1+1 (17.0.4.1+1) (build 17.0.4.1+1)

After that we updatet to the latest 17 LTS Temurin release
OpenJDK Runtime Environment Temurin-17.0.8.1+1 (17.0.8.1+1) (build 17.0.8.1+1)

but we can still reproduce it.

Here is the content of the full hs_err_pid*.log:
https://github.com/retomerz/pasetbin/blob/main/hs_err_pid215731.log

The Java code of the mentioned method (ch.abacus.abareport.Logger.logOldImpl(Level,String,Throwable))
is below [1].

Is this a known problem or should we report this via bugreport.java.com?
In case we should report it, what exact info should be provided?

Thanks

Regards
Reto

private static void logOldImpl(Level level, String message, Throwable throwable){
if (LOG_TO_SYSTEM_OUT){
System.out.println(/*NlsIgnore*/"LOG: " + level + " -> " + message);
} else {
try {
if (ULCParams.hasULCParams()){
message = ((AVSystem)((WeakReference)ULCParams.currentULCParams().properties().get(AVSystem.PARAM_STRING)).get()).getReport().getFile().getURL().toString() + " - " + message;
}
} catch (Exception e){
message = /*NlsIgnore*/"no system - " + message;
}
getLogger().log(level, message, throwable);
}

if (throwable != null){
throwable.printStackTrace();
}
}

Hi Reto,

If you think you have found a bug then please do report it through bugreport.java.com. Provide as much relevant info as you possibly can. A reproducer is much appreciated. You can find more information about what info to provide here: https://openjdk.org/guide/#filing-an-issue

Thanks,

Hello,

Thanks Douglas Simon, David Griffiths and Jesper Wilhelmsson for your time, feedback and suggestions.

I was able to create a simple reproducer [1] which cause the crash dump [2]
very often after a few seconds. Sometimes 2-3 attempts are needed.

The problem is still only reproducible with Linux OS, not Windows.
I suspect that the problem is related to the used ReentrantLock.

As I expected, the problem is not related to Adoptium/Temurin build.
It is also reproducible with latest Oracle 17 LTS build ([3]).

So I have reported it via bugreport.java.com (internal review ID: 9076126)
I think "adoptium-support" ([4]) would not be the right place for that sort of bug report.

If I receive a public JDK issues link, I will post it here.

Regards

Thanks
Reto

Hi Reto,

Thanks a lot for the reproducer!

This seems to be a C1 issue and it looks like it was fixed in JDK 21
(i.e. I could easily reproduce it with JDK 17 & 20 but not with 21).
If we're lucky it was a simple fix which can easily be downported.

Best regards,
Volker

I think it's: https://bugs.openjdk.org/browse/JDK-8310126

Verifying ...

Best regards,
Tobias

[Tobias Hartmann]

Confirmed. The issues was fixed in JDK 17.0.9, JDK 21 b29 and JDK 22 b12.

Best regards,
Tobias

[Volker Simonis]

Exactly, that was the issue!

Thanks, Tobias.
