I get this when I run trufflesqueak in MacOS 11.2.3 with the GraalVM 21.1:

How do you launch TruffleSqueak on your command line? According to your stack trace, TruffleSqueak tries to open a display, but fails because AWT is running in headless mode.

solved. For some reason the zsh session I was running graalvm in would always return sun.java2d.HeadlessGraphicsEnvironment for java.awt.GraphicsEnvironment/getLocalGraphicsEnvironment . The solution was to start a new terminal and it worked

Good, glad it's working now!
