Zendesk Java SDK client method `lookupUserByEmail` fails to find user when email address contains special characters like `+` and `-`
sample email address containing `+` and `-` characters:
someone.test+test-20220404@gmail.com

The repository that you reference is actually an open sourced repo not created or maintained by Zendesk. I'd suggest opening up an issue on the repo to get in contact with the cloudbees team.
Thanks!
