The binary at /snap/processing/8/opt/processing/lib/app/resources/jdk/bin/java indeed has no executable bit:

ls -ahl /snap/processing/8/opt/processing/lib/app/resources/jdk/bin/java 
Permissions Size User Date Modified Name
.rw-r--r--   16k root 25 apr 15:10  /snap/processing/8/opt/processing/lib/app/resources/jdk/bin/java

This is the same error seen in #1047 where this same missing executable permission surfaced when running processing in CLI mode.

snippet

// Paste your code below :)

void setup() {

}

void draw() {

}

Hi @berkes Thanks for the extensive reporting! I do not have my linux machine with me today so I will look into this a bit later but seems like a simple fix with the permissions indeed.

I have the same problem on my RPi 500 !
