Well, my understanding is that’s rather a ‘no, it also works with Java 8’.
I am not asking to change the minimum version that is supported, but currently, I have to change manually if I want to compile Graal without having to install Java 7 as well.

Is there a way to ask mx to just interpret the check as >=1.7 instead ==1.7?
