The jdk included with aarch64 release is still the wrong type as I mentioned previously but easily fixed by creating a soft link. Because I’m using Manajaro linux I just link /usr/lib/jvm/default-runtime.
[tux@monkstone ~]$ java --version
openjdk 14.0.1 2020-04-14
OpenJDK Runtime Environment (build 14.0.1+7)
OpenJDK 64-Bit Server VM (build 14.0.1+7, mixed mode)
And processing runs just fine.
