Arduino doesn’t work on Manjaro aarch64.
It just run into java.lang.NullPointerException
java-runtime is jre-openjdk-14

I am facing the same problem. This appears to be an issue in the Arduino IDE app.
Looks like there is a patch for it which is already merged and should be available in next release of Arduino IDE:

Update: Meanwhile, I installed arduino-avr-core package and its dependencies and the problem went away.
