I have replicated the change from 10.0 that you see.
Now when i press COMMAND-1 it minimizes the windows and shows in Finder, a google search determines this is a standard mac shortcut - https://support.apple.com/en-us/HT201236
Command-1: View the items in the Finder window as icons.
No change has been made to the code, so this must be due to the move from Java 8 to Java 11
I am not clear what is correct MacOS behaviour, for applications or system shortcuts to take precedence. If it is system I will need to change the shortcut mappings
Confusingly, Retreive Acoustic Ids is defined in the same way to use Command-2, this is also a standard MacOS shortcut
Command-2: View the items in a Finder window as a list.
but continues to work as before !
I have raised an issue - JAIKOZ-1268
If anyone has knowledge of if application or system shortcuts should take precedence please let me know.
