eolivelli opened a new issue #10798: URL: https://github.com/apache/pulsar/issues/10798
**Describe the bug** I am trying to upgrade from Pulsar Client 2.7.1 to Pulsar Client 2.8.0-SNAPSHOT an application that runs on a docker container based on jdk15-alpine, so with JDK15 and Alpine Linux. It crashes with a core dump. This is a regression because it used to work with Pulsar Client 2.7.1 and it prevents the application to be upgrade. The problem seems related to Netty Native ``` --------------- S U M M A R Y ------------ Command Line: nb.jar run driver=pulsar yaml=/config/pulsar.yaml config=/config/config.txt cycles=1..100 Host: Intel(R) Core(TM) i7-9750H CPU @ 2.60GHz, 10 cores, 23G, Alpine Linux v3.12 Time: Thu Jun 3 06:53:51 2021 UTC elapsed time: 3.377851 seconds (0d 0h 0m 3s) --------------- T H R E A D --------------- Current thread (0x000055edc903bb00): JavaThread "scenarios:001" [_thread_in_native, id=83, stack(0x00007f50991d6000,0x00007f50992d6aa8)] Stack: [0x00007f50991d6000,0x00007f50992d6aa8], sp=0x00007f50992d2318, free space=1008k Native frames: (J=compiled Java code, A=aot compiled Java code, j=interpreted, Vv=VM code, C=native code) C 0x0000000000003efe C [liborg_apache_pulsar_shade_netty_transport_native_epoll_x86_648601706269064153288.so+0xb487] netty_jni_util_JNI_OnLoad+0x67 C [libjava.so+0xf4bd] Java_jdk_internal_loader_NativeLibraries_load+0xdd j jdk.internal.loader.NativeLibraries.load(Ljdk/internal/loader/NativeLibraries$NativeLibraryImpl;Ljava/lang/String;ZZ)Z+0 java.base@15-ea j jdk.internal.loader.NativeLibraries$NativeLibraryImpl.open()Z+57 java.base@15-ea j jdk.internal.loader.NativeLibraries.loadLibrary(Ljava/lang/Class;Ljava/lang/String;Z)Ljdk/internal/loader/NativeLibrary;+256 java.base@15-ea j jdk.internal.loader.NativeLibraries.loadLibrary(Ljava/lang/Class;Ljava/io/File;)Ljdk/internal/loader/NativeLibrary;+51 java.base@15-ea j java.lang.ClassLoader.loadLibrary(Ljava/lang/Class;Ljava/io/File;)Ljdk/internal/loader/NativeLibrary;+31 java.base@15-ea j java.lang.Runtime.load0(Ljava/lang/Class;Ljava/lang/String;)V+61 java.base@15-ea j java.lang.System.load(Ljava/lang/String;)V+7 java.base@15-ea j org.apache.pulsar.shade.io.netty.util.internal.NativeLibraryUtil.loadLibrary(Ljava/lang/String;Z)V+5 v ~StubRoutines::call_stub V [libjvm.so+0x75dbe2] JavaCalls::call_helper(JavaValue*, methodHandle const&, JavaCallArguments*, Thread*)+0x2a2 V [libjvm.so+0xb8066b] invoke(InstanceKlass*, methodHandle const&, Handle, bool, objArrayHandle, BasicType, objArrayHandle, bool, Thread*) [clone .constprop.126]+0x85b V [libjvm.so+0xb81156] Reflection::invoke_method(oopDesc*, Handle, objArrayHandle, Thread*)+0x106 V [libjvm.so+0x814c83] JVM_InvokeMethod+0xf3 j jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Ljava/lang/reflect/Method;Ljava/lang/Object;[Ljava/lang/Object;)Ljava/lang/Object;+0 java.base@15-ea ``` **To Reproduce** In order to reproduce you have to run a Java application that boots the Pulsar Client on a docker container with an imaged based on alpine linux. **Expected behavior** The client works as for Pulsar 2.7.x **Desktop (please complete the following information):** - Docker, Alpine linux -- This is an automated message from the Apache Git Service.
