我无法让JNI与Cygwin的g++一起使用-导致对cygwin1.dll的依赖，这与JNI机制冲突，导致碰撞.但是使用/bin/x86_64-w64-mingw32-g++.exe可以解决我的问题.

I couldn't get JNI to work with Cygwin's g++ -- that induces a dependency on cygwin1.dll, which ***es with the JNI mechanism, causing a crash. But using /bin/x86_64-w64-mingw32-g++.exe fixed the problem for me.
