Hi Chris,

maybe you could sneak this patch into upstream, it’s a fix for an issue where the VM segfaults when it tries to print a string with a null value array.
It confused me for a while while looking for another problem...
I think it got introduced when the String class was changed - because now it needs to look at the value array to determine the length.
