java version "1.8.0_431" Java(TM) SE Runtime Environment (build 1.8.0_431-b10) Java HotSpot(TM) 64-Bit Server VM (build 25.431-b10, mixed mode)

运行main时日志为

[2024-11-15T20:35:44.666] DEBUG Attached thread main (ThreadId(1)). 1 threads attached [2024-11-15T20:35:44.670] DEBUG VM option: -Djava.library.path=. [2024-11-15T20:35:44.670] DEBUG VM option: -XX:+DisableAttachMechanism [2024-11-15T20:35:44.670] DEBUG VM option: -Dfile.encoding=UTF-8 [2024-11-15T20:35:44.670] DEBUG VM option: -Xms128M [2024-11-15T20:35:44.670] DEBUG VM option: -Xmx128M [2024-11-15T20:35:44.670] DEBUG Runtime vm param check pass! 进程已结束，退出代码为 139 (interrupted by signal 11:SIGSEGV)

定位原因为 https://github.com/xtherk/rust-jni-example/blob/master/src/main.rs#L106 此处没有真正取到jvmti，而L108这里没能check出来，最终在L110崩溃

我是arm的环境，也许与你的开发环境有些差异

不好意思，我没mac，不然能查一下问题。我是在windows x64环境下开发的
