easily enough 'fixed' upgrading from solr 8.10.1 -> 8.11.1, cures this reproducible problem i'm still not clear on the specific cause; i'm guessing atm it's to do with my recent/local upgrades of 'java-latest' pkgs from v17 -> v18

solr 8x -> 9.0.0 upgrade; BasicAuth security FAILs @ "o.a.s.s.BasicAuthPlugin Bad auth credentials supplied in Authorization header" ?
