JVM crash couldn't analyze

[ajantha-bhat]

HI, I use pyjnius in my project.

when I run my function , I get a JVM crash randomly with below message.

A fatal error has been detected by the Java Runtime Environment:

SIGSEGV (0xb) at pc=0x00007f1dad332b3f, pid=21666, tid=0x00007f105e7fc700

JRE version: Java(TM) SE Runtime Environment (8.0_144-b01) (build 1.8.0_144-b01) Java VM: Java HotSpot(TM) 64-Bit Server VM (25.144-b01 mixed mode linux-amd64 ) Problematic frame: V [libjvm.so+0x6d5b3f] jni_invoke_nonstatic(JNIEnv_, JavaValue, _jobject*, JNICallType, _jmethodID*, JNI_ArgumentPusher*, Thread*)+0x1af

problematic frame is in libjvm.so, how to know what is the problem ? Also observed that pyjnius cannot give me the whole exception callstack, it just returns me the error message. is there a way to get full callstack ?

please find the update. I was able to generate the core dump .

below is the core dump call stack.

can you tell me the problem from below stack ? It's a random jvm crash I am getting
