Unable to open Pattypan 22.03 (and .02) with M2 Mac

[trnstlntk]

I'm unable to open Pattypan 22.03 on my M2 Mac. Specs are:

When attempting to open pattypan.jar by double-clicking, I get:

When attempting to open in the Terminal by entering java -jar pattypan\ 22.03.jar I get:

I get exactly the same behavior when trying to open Pattypan 22.02.

[PythonCoderAS]

Same behavior with M1. Some digging shows that openjfx/javafx-maven-plugin#112 and https://gluonhq.com/javafx-for-apple-m1/

[PythonCoderAS]

I just built a version for M1/M2. Built it yourself:

brew install ant # If you don't have ant
cd /tmp/
git clone https://github.com/yarl/pattypan.git
cd pattypan
wget https://download2.gluonhq.com/openjfx/20/openjfx-20_osx-aarch64_bin-sdk.zip
ant

[psubhashish]

22.02 worked actually with an initial hiccup, not related to Pattypan. (updated to add 22.02 tested on Intel Mac and not M2)

I am still not able to install it.

anish@ip-192-xxx pattypan % java -jar pattypan.jar
Error: LinkageError occurred while loading main class pattypan.Launcher
java.lang.UnsupportedClassVersionError: pattypan/Launcher has been compiled by a more recent version of the Java Runtime (class file version 64.0), this version of the Java Runtime only recognizes class file versions up to 61.0

Same error on Mac Intel.

Cloned and compiled it as suggested by @PythonCoderAS but the resulting jar fails when launched.

The instructions are only for M1/M2 macs. For intel, use this URL: https://download2.gluonhq.com/openjfx/20/openjfx-20_osx-x64_bin-sdk.zip

Thanks. Now as error i get:
Exception in thread "main" java.lang.UnsupportedClassVersionError: pattypan/Launcher has been compiled by a more recent version of the Java Runtime (class file version 65.0), this version of the Java Runtime only recognizes class file versions up to 52.0
I updated Java to the latest version on my mac (Java 8.381) but still doesn't work. I got that Java 8 is also called 52, but then I don't understand how to update it to Java 21 (65)

EDIT: found how to fix it, it is needed to update not Java but JDK. Mac download at this link: https://www.oracle.com/java/technologies/downloads/#jdk21-mac

Installing the JDK developer kit fixed a similar error for me on a Windows machine
