For this kind of methods you need the offset and length to check if the range is actually tainted (maybe there's no intersection so there is indeed no XSS).

Are the write methods inherited from Writer used by the compilation of JSPs? (maybe we can skip them altogether and remove the problem)

Thanks for the advice! I think that the offset methods are not used in JSP, I will remove the callSites for this PR
