Hi,

I am trying to start up the server but getting below error.

I am running:

I haven't found anything in existing issues regarding this.

Let me know if any more details required.

Any help will be highly appreciated as I have already spent too much time to figure this out.

Do you have a file called /Library/Java/JavaVirtualMachines/openjdk-17.jdk/Contents/Home/lib/libzip.so or any filed called libzip.so within that java home directory ? That shared library should contain the initIDs function : https://github.com/openjdk/jdk17/blob/4afbcaf55383ec2f5da53282a1547bac3d099e9d/src/java.base/share/native/libzip/Inflater.c#L48-L55 .

This is basically where it fails :

https://github.com/openjdk/jdk17/blob/4afbcaf55383ec2f5da53282a1547bac3d099e9d/src/java.base/share/classes/java/util/zip/Inflater.java#L114-L117

@rgrunber Thanks. That was it. I had libzip.dylib (MacOS) already installed as dependency of other software (installed using homebrew) so openjdk17 (also installed using homebrew) was symlinking to that lib. I removed said software and reinstalled openjdk17 which downloaded the correct libzip.dylib which has this method.

For anyone else facing the same issue, you can run below command to see if the method is present in a lib (on macOS):

objdump -t libzip.dylib | grep -i init

Closing this issue!.
