install issue on mac

[peter...@gmail.com]

Hi, I have a compatibility problem with owlcms_44.1.0-rc03 and my Java version. What am I doing wrong?

I installed this version of the JRE: https://github.com/adoptium/temurin11-binaries/releases/tag/jdk-11.0.20.1%2B1

This is the error I get:

pete:owlcms2 peterrohne$ /Library/Java/JavaVirtualMachines/temurin-11.jre/Contents/Home/bin/java -DmemoryMode=true -DinitialData=LARGEGROUP_DEMO -jar owlcms.jar

Error: LinkageError occurred while loading main class app.owlcms.Main

java.lang.UnsupportedClassVersionError: app/owlcms/Main has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 55.0

Thanks for your help!

Java version 17 is required for version 44 (there was a major update of the user interface library which in turn requires Java 17)

Downloading a .pkg file and double-click on it should work.
