Tests failing with UnknownHostException: localhost #478

Closed iocanel closed 7 months ago

Not sure what triggers that on my machine, but I do get:

Wow.... I've never seen this one...

iocanel commented 7 months ago

The issue seems to be a malformed entry in my /etc/hosts file. More specifically the use of , as a separator between host names for 127.0.0.1. Still, weird as every other piece of software still manages to resolve localhost.

Maybe wiremock or one of its dependencies is directly parsing that file.
