Native crash (SIGSEGV) on process shutdown

[KF-Miyata]

Describe the bug Runtime behavior is fine during execution, but a native crash occurs on program exit.

# A fatal error has been detected by the Java Runtime Environment:
#
#  SIGSEGV (0xb) at pc=0x00007f310ed1610d, pid=252732, tid=0x00007f3140569700
#
# JRE version: OpenJDK Runtime Environment (8.0_432-b06) (build 1.8.0_432-432-b06)
# Java VM: OpenJDK 64-Bit Server VM (25.432-b06 mixed mode linux-amd64 compressed oops)
# Problematic frame:
# C  [libwebrtc-java-linux-x86_642121276466645068163.so+0x4d010d]  jni::JavaFactory<webrtc::RtpTransceiverInterface>::~JavaFactory()+0x2d
#
# Failed to write core dump. Core dumps have been disabled. To enable core dumping, try "ulimit -c unlimited" before starting Java again
#
# An error report file with more information is saved as:
# /home/dev/hs_err_pid252732.log

To Reproduce Minimal code:

import dev.onvoid.webrtc.media.audio.AudioProcessing;

public class Repro {
    public static void main(String[] args) {
        AudioProcessing ap = new AudioProcessing();
        ap.dispose();
    }
}

Gradle dependencies:

implementation "dev.onvoid.webrtc:webrtc-java:0.14.0"
implementation group: "dev.onvoid.webrtc", name: "webrtc-java", version: "0.14.0", classifier: "linux-x86_64"

Expected behavior Process should exit cleanly with no crash

Desktop (please complete the following information):

• OS: AlmaLinux 8.10 (Cerulean Leopard)
• Architecture: x86_64

Thanks for the report! I see that you are using the OpenJDK Runtime Environment (8.0_432-b06), which is quite outdated.

Unfortunately, I can't reproduce the issue on AlmaLinux 8 using newer JDKs. I will try it with JDK 8 later.

Could you also try to reproduce this behaviour with JDK 17, for example?

[KF-Miyata]

Thank you for your reply, and I apologize for the delay. I have tested with JDK 17, and I can confirm that the issue does not occur with that version.

I'm also seeing SIGSEGV on JVM 25

[kalgecin]

but mine comes from peerConnectionFactory.dispose(). I will try to reproduce with minimal code and probably open a new ticket

[kalgecin]

Figured out my problem. I was trying to dispose peer connection factory from within PeerConnectionObserver (that was passed into factory.createPeerConnection). Changing the logic around fixed the problem.

[selfancy]

Can it be compatible with Java 8?
