**Describe the bug (描述bug)** 使用jni加载brpc.so时报pthread_mutex_lock未定义， 使用export LD_PRELOAD=/usr/lib64/libbrpc.so 解决了加载的问题，但java线程在退出时core掉了。 **To Reproduce (复现方法)** 使用jni加载brpc.so 并在java中使用线程，观察 线程退出时会不会产生core **Expected behavior (期望行为)** 能够 正常使用 **Versions (各种版本)** OS: Compiler: brpc: protobuf: **Additional context/screenshots (更多上下文/截图)** #0 __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:51 https://github.com/apache/brpc/issues/1 0x00007f259f32ff95 in __GI_abort () at abort.c:79 https://github.com/apache/brpc/issues/2 0x00007f259b95be09 in os::abort(bool) () from /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.302.b08-0.el7_9.x86_64/jre/lib/amd64/server/libjvm.so https://github.com/apache/brpc/issues/3 0x00007f259bb8367a in VMError::report_and_die() () from /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.302.b08-0.el7_9.x86_64/jre/lib/amd64/server/libjvm.so https://github.com/apache/brpc/issues/4 0x00007f259b965fb5 in JVM_handle_linux_signal () from /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.302.b08-0.el7_9.x86_64/jre/lib/amd64/server/libjvm.so https://github.com/apache/brpc/issues/5 0x00007f259b958fc8 in signalHandler(int, siginfo_t*, void*) () from /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.302.b08-0.el7_9.x86_64/jre/lib/amd64/server/libjvm.so https://github.com/apache/brpc/issues/6 https://github.com/apache/brpc/pull/7 0x0000000000000000 in ??
