Unable to run MinimServer on Mac Mini M1 w/ Azul JVM

Unable to run MinimServer on Mac Mini M1 w/ Azul JVM
I have a very old Mac Mini that I have been running MinimServer on that I am replacing with a new M1 model. In the process of setting it up I installed MinimServer and tried to launch it. I got a dialog about needed to install a version of Java greater than 8.

Since this box is pristine I looked around and it looked like the only native M1 JVM was from Azul so I downloaded that and installed it. I have validated that I can use that javac compiler and java command to run a simple command. However, when I try to double click MinimServer.app I got an error dialog saying:

LibjliOpenError

If I look in my $HOME/Library/MinimServer directory, minim-server.log has this in it:

cat ~/Library/MinimServer/minimserver-out.log
2021-04-08 21:13:51.632 MinimJavaLauncher[14784:1799906] libjliFile: /Library/Java/JavaVirtualMachines/zulu-8.jdk/Contents/Home/jre/lib/jli/libjli.dylib
2021-04-08 21:13:51.632 MinimJavaLauncher[14784:1799906] libjliOpenError: dlopen(/Library/Java/JavaVirtualMachines/zulu-8.jdk/Contents/Home/jre/lib/jli/libjli.dylib, 1): no suitable image found. Did find:
/Library/Java/JavaVirtualMachines/zulu-8.jdk/Contents/Home/jre/lib/jli/libjli.dylib: mach-o, but wrong architecture
/Library/Java/JavaVirtualMachines/zulu-8.jdk/Contents/Home/jre/lib/jli/libjli.dylib: stat() failed with errno=9

That kind of makes me wonder whether when the MinimServer launcher that is starting it is declaring the architecture of the lib ... or that because an x86 binary is trying to load the JVM it won't let it because the target architecture doesn't match.

Any ideas here? Is there a way to just launch the MinimServer app from the command line as a pure Java thing?

RE: Unable to run MinimServer on Mac Mini M1 w/ Azul JVM
Your diagnosis of the cause of the problem is correct. The MinimServer launcher for macOS is expecting to find an Intel JVM.

It should work if you remove the Azul JVM and install Java for macOS from this page. The M1 chip can run a JVM built for Intel using the Rosetta emulator.

Thank you for the precise response - it saves me a lot of time. I'll uninstall the Azul JVM and try the one you pointed me to. Two requests:

(1) Please make an M1 or universal binary available sometime in 2021. I know these machines are fairly new and there are few out there in the wild. I'm pretty sure there are cloud instances you can get access to for development w/o buying one. Virtually the only reason my M1 Mac Mini exists is to run MinimServer. I am sure that JIT on top of JIT will work, but ...

(2) If at all possible, somewhere in the release notes provide a command line to invoke the application jar file so we aren't forced to use the wrapper application. If that makes the license check not work, then just tell us and we'll know why. I certainly appreciate the complexity of multi-platform application deliver.

And just in case anyone else finds this as relating to an M1 Mac ... the Oracle JVM version 8 from the page referenced in this thread allowed MinimServer to run just fine.

RE: Unable to run MinimServer on Mac Mini M1 w/ Azul JVM
I am intending to add native M1 support at some point but at present there is no timescale for this.

You could try launching MinimServer from a Terminal window using the following commands:

cd /Applications/MinimServer.app/Contents/Java
java -jar mserver.jar

This will not affect how licensing is handled. Doing this is untested and unsupported.

Hello,
I downloaded Minimserver in order to try it on a M1 Mac Mini. I installed Java 8 as well, but I encounter the same problem, and get the same "LibjliOpenError" message.
Same error occurs when I launch Minimwatch.
I ran the terminal commande, but it does not work.

I have Azul installed on my M1 Mini, and I don't know how to remove it from the drive, in order to make Minimserver work with Java 8.
