Environments using the Build-Name Setter Plugin with long build names cause the Build Executor Table layout to become jumbled.

Issue can be recreated by:

Download and start Jenkins Jenkins v1.596.1 (or any version >= 1.593)

Install the build name setter plugin

Create a new job named: JOB-VERSION-004.1000.000-CE-Test

Enable Set Build Name in the Build Environment section with the following:
#${BUILD_NUMBER}${PROPFILE,file="property.txt",property="myName"}

Create the property.txt file containing: myName=#1074_("version-4.100.0-1754.cr.el6")
and place it in the build workspace root.

In the Build section add a Execute Shell step with sleep 60s

Save the job and run it.

View the Jenkins Dashboard (Jenkins_URL, i.e. localhost:8080) to see the Build Executor.
