[JENKINS-51827] Randon String in branch name in multibranch pipeline on jenkins master server

Hi,

I am using multibranch pipeline job. In our Organization create the branch name with the following pattern (/). e.g "integration/treatmentResume"

Also, I am using the custom workspace folder.

when I check this branch name on Jenkins master server to access the archive artifact then I got the below branch name.

*Modified Branch Name :- "*integration-.agrm62.atmentResume"

Original Branch Name:- "integration/treatmentResume" 

Path :- var/lib/jenkins/jobs//branches/

Please let me know what the logic behind this.
