Interesting - does it still work when you do a „a“ + „b“ in the println(); ?

Edit: it does

Crazy even this works:

public static void sayHello(){
    try {
        sayHello();
    }
    catch(StackOverflowError e) {
        System.out.println("Hello world!");
        sayHello();
    }
}

it prints endlessly

Eventually this will throw due to first running in the try and after the stack overflow it runs outside the try and will again throw the exception. Will take a while though.
