I believe this issue is described at
https://commons.apache.org/proper/commons-compress/zip.html, although the

Steps to reproduce:
{noformat}
>stopwords.txt
zip -r - * | curl -X POST --header "Content-Type:application/octet-stream"
--data-binary @-
"http://localhost:8983/solr/admin/configs?action=UPLOAD&name=c1";
