Calling Golang from Java using JNI on Windows leads to "A dynamic link library (DLL) initialization routine failed"

Question

I created the following example project to test out calling Golang code from Java using JNI: https://github.com/blaubaer/golang-jni

When I call build.cmd I receive an error message like this:

Exception in thread "main" java.lang.UnsatisfiedLinkError: [...]\out\hello.dll: A dynamic link library (DLL) initialization routine failed
        at java.base/java.lang.ClassLoader$NativeLibrary.load0(Native Method)
        at java.base/java.lang.ClassLoader$NativeLibrary.load(ClassLoader.java:2430)
        at java.base/java.lang.ClassLoader$NativeLibrary.loadLibrary(ClassLoader.java:2487)

        at java.base/java.lang.System.loadLibrary(System.java:1867)
        at Hello.<clinit>(Hello.java:3)

Used environment:

• Windows: 10.0.17763, Build 17763, 64bit
• Golang: 1.11.5, windows/amd64
• Java: 11.0.2 2019-01-15 LTS, 64-Bit
• MinGW-w64: x86_64-8.1.0-win32-sjlj-rt_v6-rev0

Thanks!

Answer 1

It seems to be related to a bug inside Golang itself. There is currently a Pull Request opened runtime: This change modifies Go to fix c-shared dll crash on x64 windows #30944 where I can approve that this will fix the issue.
