#1325 OmegaT 6.1.0 beta won't launch on macOS 27.0 beta 3

[Doctor Fedora]

Existing Reddit thread with previous attempts at addressing this: https://www.reddit.com/r/OmegaT/s/1Cj3qOG7ua

When trying to launch OmegaT 6.1.0 on my M1 Macbook Air running macOS 27.0 beta 3, the dock icon bounces a few times before failing. When running it directly from the terminal using the java command, it gives the log found at https://pastebin.com/bfWVaNQ9

I was told on Reddit to paste some parts of the log for reference:

For reference, my M1 iMac with basically an identical hardware/software profile still launches OmegaT just fine. Is there an issue with my Java installation? Or is there perhaps some sort of mismatch in the DeepL plugin version I'm using on both computers…?
