Is there a solution around Pentaho 9.3 Spoon errors related to Apple Silicon M1 ARM?

Question

Installed Pentaho Data Integration 9.3 on Mac OS Monterey on a MacBook Pro M1 (Apple Silicon.)

I am running OpenJDK 11:

Openjdk version "11.0.15" 2022-04-19

OpenJDK Runtime Environment (build 11.0.15+10)

OpenJDK 64-Bit Server VM (build 11.0.15+10, mixed mode)

The install.sh process runs without error. However, after install, trying to execute the spoon.sh process, the following errors occur...

WARNING: Using java from path

Has anyone run into this issue and are there any known workarounds?

Download latest swt for arm64 support from here

https://www.eclipse.org/downloads/download.php?file=/eclipse/downloads/drops4/S-4.25M1-202207061800/swt-4.25M1-cocoa-macosx-aarch64.zip&mirror_id=518

unzip it, get swt.jar and Put it under /path_to_your_data-integration/libswt/osx64/ and delete the one thats there.

Than using rosseta shell, guide how to set up rosseta can be found here: https://stackoverflow.com/a/68571463/19586128

start the spoon.sh with required configurations

If you use java 8 It will complain first with: Exception in thread "main" java.lang.UnsupportedClassVersionError: org/eclipse/swt/widgets/Control has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

I update my JAVA_HOME to 18 (17 works too) and it worked

This worked for me, but please feel free to ask if it does not work and i can help more with this
