Thanks for the fix.
LGTM

nit suggestion: I think LICENSE/NOTICE and .asf.yaml are also safe to ignore and might fit here

[snuyanzin]

I was thinking about it however the answer is no

the reason is that RAT license check in compile.sh parses them

and changes in LICENSE/NOTICE might lead to failure

Makes sense, thanks @snuyanzin
