So the reason you need this to traverse the AST and crash on the null pointers (when the patch is not applied right?)
I think you could comment something like traverse the AST to catch certain bugs like poorly (not) imported subtrees. 
If we do not want to actually print the whole tree (because it might be noisy) you can also try using a no-op recursive AST visitor.
