Thanks for reporting this issue. This crash is log means that the Unicode mapping is not available for one of the fonts and is handled internally with the correct generation of the validation report.

But I do agree this looks a bit confusing. We have refactored this part to avoid java.io.IOException and non-informative logs. The changes are available in the latest dev version and will be included in the next release.
