The new version is out: https://www.eu.apache.org/dist/xalan/xalan-j/source/ Reproducible: Always
Done.
An enormous collection of 404 errors results from this. 6+ minutes of fetch failure. Is 2.7.2 still current? Has it been pulled in favour of something newer? I would paste the motley collection of error messages here, but it is longer than 16384 characters.
Created attachment 405994 [details] fetch-failure.txt Evidence of 6 minutes of fetch failure.
Fixed. Sincere apologies for that. Knowing that xalan-serializer uses the same tarball as xalan, I meant to double check the SRC_URI but forgot. Portage probably shouldn't try so many mirrors, if it's not found it on 5 of them, it's probably not going to find it at all.
