Unable to create jobs when branch contains % in the name

[dhumeniuk]

I'm using Jenkins 1.532.1.

At first I thought it was a problem in general, but noticed the first branch had a % in it. I created a new branch that would be tried first and it seemed to work.

Console output for the sync job:

getting project names from https://xxx.yyy.com/jenkins/api/json
Creating missing job: xxxyyy-Docs-some%branch from xxxyyyGit-Docs-master
Trying to find crumb: https://xxx.yyy.com/jenkins/crumbIssuer/api/json
Couldn't find crumbIssuer for jenkins. Just moving on it may not be needed.

Exception in thread "main" java.lang.Exception: Unexpected failure on https://xxx.yyy.com/jenkins/createItem: HTTP/1.1 400 Bad Request 400
