If you build OpenJDK 11 with the patch, I can test it on the following 
32-bit ARM devices:

- Raspberry Pi 2 Model B Rev 1.1 (BCM2836 quad-core ARM Cortex-A7)
- Kobo Touch N905C (i.MX507 single-core ARM Cortex-A8)

That old 2013 Kobo Touch e-reader is where the error first occurred back 
in May 2018.

Would that help? I don't know enough to comment on the code.
