parameterizing the branch name for build job & its effect in SCM Polling process

[niristotle okram]

Some version info: 

Git Client Plugin : 1.10.1

Git Plugin          :  2.2.5

jenkins              : 1.589

I have a simple jenkins job to perform the maven deploy Or maven release plugins from *a branch like (master or release branch) . Now, i changed it, the branch name is parameterized. Either the master or the release branch is specified before the job is manually triggered.  Some screenshots of the job's conf page.

You will see from the screenshots that there is no default branch specified for the job. As of now, i see that the SCM polling is triggering the build from the master branch. i know that the dev are pushing on the master. I haven't had a chance to verify if the SCM polling triggers a build job/process when there is push to release branch.  

Then i came across this https://issues.jenkins-ci.org/browse/JENKINS-14276 , i am lost in the comments. Please let me know what was the fix for this? Any particular version of "Git Plugin"? 

thanks
