Running java -jar leads to this exception.

The program shows up. But, pressing assemble button does not work.

Nothing shows up on execute window after pressing assemble.

Instead, some error messages pop up in the terminal after pressing the assemble button.

My default java is OpenJDK 17.

I try both downloading the rars file provided and compiling a new rars file (by running "./build-jar.sh"). Both does not help.

Furthermore, I notice some commands are not recognized by the assembler.
